For example: "setenv stdin serial,nc". NOTE: No spaces +are allowed around the comma(s)! + +The length of the list is limited by malloc(), since the array used +is allocated and freed dynamically. + +It should be possible to specify any device which console_assign() +finds acceptable, but the code has only been tested with serial and +nc. + +iomux_doenv() prevents multiple use of the same device, e.g. "setenv +stdin nc,nc,serial" will discard the second nc. iomux_doenv() is +not able to modify the environment, however, so that "pri stdin" still +shows "nc,nc,serial". + +The major change in common/console.c was to modify fgetc() to call +the iomux_tstc() routine in a for-loop. iomux_tstc() in turn calls +the tstc() routine for every registered device, but exits immediately +when one of them returns true. fgetc() then calls iomux_getc(), +which calls the corresponding getc() routine. fgetc() hangs in +the for-loop until iomux_tstc() returns true and the input can be +retrieved. + +Thus, a user can type into any device registered for stdin. No effort +has been made to demulitplex simultaneous input from multiple stdin +devices. + +fputc() and fputs() have been modified to call iomux_putc() and +iomux_puts() respectively, which call the corresponding output +routines for every registered device. + +Thus, a user can see the ouput for any device registered for stdout +or stderr on all devices registered for stdout or stderr. As an +example, if stdin=serial,nc and stdout=serial,nc then all output +for serial, e.g. echos of input on serial, will appear on serial and nc. + +Just as with the old console code, this statement is still true: +If not defined in the environment, the first input device is assigned +to the 'stdin' file, the first output one to 'stdout' and 'stderr'. + +If CONFIG_SYS_CONSOLE_IS_IN_ENV is defined then multiple input/output +devices can be set at boot time if defined in the environment. + +CAVEATS +------- + +Note that common/iomux.c calls console_assign() for every registered +device as it is discovered. This means that the environment settings +for application consoles will be set to the last device in the list. + +On a slow machine, such as MPC852T clocked at 66MHz, the overhead associated +with calling tstc() and then getc() means that copy&paste will normally not +work, even when stdin=stdout=stderr=serial. +On a faster machine, such as a sequoia, cut&paste of longer (about 80 +characters) lines works fine when serial is the only device used. + +Using nc as a stdin device results in even more overhead because nc_tstc() +is quite slow. Even on a sequoia cut&paste does not work on the serial +interface when nc is added to stdin, although there is no character loss using +the ethernet interface for input. In this test case stdin=serial,nc and +stdout=serial. + +In addition, the overhead associated with sending to two devices, when one of +them is nc, also causes problems. Even on a sequoia cut&paste does not work +on the serial interface (stdin=serial) when nc is added to stdout (stdout= +serial,nc). diff --git a/doc/README.mpc8641hpcn b/doc/README.mpc8641hpcn index 5ac39e6..d8fe0a4 100644 --- a/doc/README.mpc8641hpcn +++ b/doc/README.mpc8641hpcn @@ -134,15 +134,15 @@ For 36-bit-enabled u-boot, the virtual map is the same as for 32-bit.

You add the CRC to the message, + * and the whole thing (message+CRC) is a multiple of the given + * CRC polynomial. To check the CRC, you can either check that the + * CRC matches the recomputed value, *or* you can check that the + * remainder computed on the message+CRC is 0. This latter approach + * is used by a lot of hardware implementations, and is why so many + * protocols put the end-of-frame flag after the CRC. + * + * It's actually the same long division you learned in school, except that + * - We're working in binary, so the digits are only 0 and 1, and + * - When dividing polynomials, there are no carries. Rather than add and + * subtract, we just xor. Thus, we tend to get a bit sloppy about + * the difference between adding and subtracting. + * + * A 32-bit CRC polynomial is actually 33 bits long. But since it's + * 33 bits long, bit 32 is always going to be set, so usually the CRC + * is written in hex with the most significant bit omitted. (If you're + * familiar with the IEEE 754 floating-point format, it's the same idea.) + * + * Note that a CRC is computed over a string of *bits*, so you have + * to decide on the endianness of the bits within each byte. To get + * the best error-detecting properties, this should correspond to the + * order they're actually sent. For example, standard RS-232 serial is + * little-endian; the most significant bit (sometimes used for parity) + * is sent last. And when appending a CRC word to a message, you should + * do it in the right order, matching the endianness. + * + * Just like with ordinary division, the remainder is always smaller than + * the divisor (the CRC polynomial) you're dividing by. Each step of the + * division, you take one more digit (bit) of the dividend and append it + * to the current remainder. Then you figure out the appropriate multiple + * of the divisor to subtract to being the remainder back into range. + * In binary, it's easy - it has to be either 0 or 1, and to make the + * XOR cancel, it's just a copy of bit 32 of the remainder. + * + * When computing a CRC, we don't care about the quotient, so we can + * throw the quotient bit away, but subtract the appropriate multiple of + * the polynomial from the remainder and we're back to where we started, + * ready to process the next bit. + * + * A big-endian CRC written this way would be coded like: + * for (i = 0; i < input_bits; i++) { + * multiple = remainder & 0x80000000 ? CRCPOLY : 0; + * remainder = (remainder << 1 | next_input_bit()) ^ multiple; + * } + * Notice how, to get at bit 32 of the shifted remainder, we look + * at bit 31 of the remainder *before* shifting it. + * + * But also notice how the next_input_bit() bits we're shifting into + * the remainder don't actually affect any decision-making until + * 32 bits later. Thus, the first 32 cycles of this are pretty boring. + * Also, to add the CRC to a message, we need a 32-bit-long hole for it at + * the end, so we have to add 32 extra cycles shifting in zeros at the + * end of every message, + * + * So the standard trick is to rearrage merging in the next_input_bit() + * until the moment it's needed. Then the first 32 cycles can be precomputed, + * and merging in the final 32 zero bits to make room for the CRC can be + * skipped entirely. + * This changes the code to: + * for (i = 0; i < input_bits; i++) { + * remainder ^= next_input_bit() << 31; + * multiple = (remainder & 0x80000000) ?

CRCPOLY : 0; + * remainder = (remainder << 1) ^ multiple; + * } + * } + * If the input is a multiple of 32 bits, you can even XOR in a 32-bit + * word at a time and increase the inner loop count to 32. + * + * You can also mix and match the two loop styles, for example doing the + * bulk of a message byte-at-a-time and adding bit-at-a-time processing + * for any fractional bytes at the end. + * + * The only remaining optimization is to the byte-at-a-time table method. + * Here, rather than just shifting one bit of the remainder to decide + * in the correct multiple to subtract, we can shift a byte at a time. + * This produces a 40-bit (rather than a 33-bit) intermediate remainder, + * but again the multiple of the polynomial to subtract depends only on + * the high bits, the high 8 bits in this case. + * + * The multile we need in that case is the low 32 bits of a 40-bit + * value whose high 8 bits are given, and which is a multiple of the + * generator polynomial. This is simply the CRC-32 of the given + * one-byte message. + * + * Two more details: normally, appending zero bits to a message which + * is already a multiple of a polynomial produces a larger multiple of that + * polynomial. To enable a CRC to detect this condition, it's common to + * invert the CRC before appending it. This makes the remainder of the + * message+crc come out not as zero, but some fixed non-zero value. + * + * The same problem applies to zero bits prepended to the message, and + * a similar solution is used. Instead of starting with a remainder of + * 0, an initial remainder of all ones is used. As long as you start + * the same way on decoding, it doesn't make a difference. + */ + +#ifdef UNITTEST + +#include <stdlib.h> +#include <stdio.h> + +#ifdef UBI_LINUX /*Not used at present */ +static void +buf_dump(char const *prefix, unsigned char const *buf, size_t len) +{ + fputs(prefix, stdout); + while (len--) + printf(" %02x", *buf++); + putchar('\n'); + +} +#endif + +static void bytereverse(unsigned char *buf, size_t len) +{ + while (len--) { + unsigned char x = bitrev8(*buf); + *buf++ = x; + } +} + +static void random_garbage(unsigned char *buf, size_t len) +{ + while (len--) + *buf++ = (unsigned char) random(); +} + +#ifdef UBI_LINUX /* Not used at present */ +static void store_le(u32 x, unsigned char *buf) +{ + buf[0] = (unsigned char) x; + buf[1] = (unsigned char) (x >> 8); + buf[2] = (unsigned char) (x >> 16); + buf[3] = (unsigned char) (x >> 24); +} +#endif + +static void store_be(u32 x, unsigned char *buf) +{ + buf[0] = (unsigned char) (x >> 24); + buf[1] = (unsigned char) (x >> 16); + buf[2] = (unsigned char) (x >> 8); + buf[3] = (unsigned char) x; +} + +/* + * This checks that CRC(buf + CRC(buf)) = 0, and that + * CRC commutes with bit-reversal.

It also implements handy functions for reading and writing UBI + * headers. + * + * We are trying to have a paranoid mindset and not to trust to what we read + * from the flash media in order to be more secure and robust. So this unit + * validates every single header it reads from the flash media. + * + * Some words about how the eraseblock headers are stored. + * + * The erase counter header is always stored at offset zero. By default, the + * VID header is stored after the EC header at the closest aligned offset + * (i.e. aligned to the minimum I/O unit size). Data starts next to the VID + * header at the closest aligned offset. But this default layout may be + * changed. For example, for different reasons (e.g., optimization) UBI may be + * asked to put the VID header at further offset, and even at an unaligned + * offset. Of course, if the offset of the VID header is unaligned, UBI adds + * proper padding in front of it. Data offset may also be changed but it has to + * be aligned. + * + * About minimal I/O units. In general, UBI assumes flash device model where + * there is only one minimal I/O unit size. E.g., in case of NOR flash it is 1, + * in case of NAND flash it is a NAND page, etc. This is reported by MTD in the + * @ubi->mtd->writesize field. But as an exception, UBI admits of using another + * (smaller) minimal I/O unit size for EC and VID headers to make it possible + * to do different optimizations. + * + * This is extremely useful in case of NAND flashes which admit of several + * write operations to one NAND page. In this case UBI can fit EC and VID + * headers at one NAND page. Thus, UBI may use "sub-page" size as the minimal + * I/O unit for the headers (the @ubi->hdrs_min_io_size field). But it still + * reports NAND page size (@ubi->min_io_size) as a minimal I/O unit for the UBI + * users. + * + * Example: some Samsung NANDs with 2KiB pages allow 4x 512-byte writes, so + * although the minimal I/O unit is 2K, UBI uses 512 bytes for EC and VID + * headers. + * + * Q: why not just to treat sub-page as a minimal I/O unit of this flash + * device, e.g., make @ubi->min_io_size = 512 in the example above? + * + * A: because when writing a sub-page, MTD still writes a full 2K page but the + * bytes which are no relevant to the sub-page are 0xFF. So, basically, writing + * 4x512 sub-pages is 4 times slower then writing one 2KiB NAND page. Thus, we + * prefer to use sub-pages only for EV and VID headers. + * + * As it was noted above, the VID header may start at a non-aligned offset. + * For example, in case of a 2KiB page NAND flash with a 512 bytes sub-page, + * the VID header may reside at offset 1984 which is the last 64 bytes of the + * last sub-page (EC header is always at offset zero). This causes some + * difficulties when reading and writing VID headers. + * + * Suppose we have a 64-byte buffer and we read a VID header at it. We change + * the data and want to write this VID header out. As we can only write in + * 512-byte chunks, we have to allocate one more buffer and copy our VID header + * to offset 448 of this buffer. + * + * The I/O unit does the following trick in order to avoid this extra copy. + * It always allocates a @ubi->vid_hdr_alsize bytes buffer for the VID header + * and returns a pointer to offset @ubi->vid_hdr_shift of this buffer. When the + * VID header is being written out, it shifts the VID header pointer back and + * writes the whole sub-page. + */ + +#ifdef UBI_LINUX +#include <linux/crc32.h> +#include <linux/err.h> +#endif + +#include <ubi_uboot.h> +#include "ubi.h" + +#ifdef CONFIG_MTD_UBI_DEBUG_PARANOID +static int paranoid_check_not_bad(const struct ubi_device *ubi, int pnum); +static int paranoid_check_peb_ec_hdr(const struct ubi_device *ubi, int pnum); +static int paranoid_check_ec_hdr(const struct ubi_device *ubi, int pnum, + const struct ubi_ec_hdr *ec_hdr); +static int paranoid_check_peb_vid_hdr(const struct ubi_device *ubi, int pnum); +static int paranoid_check_vid_hdr(const struct ubi_device *ubi, int pnum, + const struct ubi_vid_hdr *vid_hdr); +static int paranoid_check_all_ff(struct ubi_device *ubi, int pnum, int offset, + int len); +#else +#define paranoid_check_not_bad(ubi, pnum) 0 +#define paranoid_check_peb_ec_hdr(ubi, pnum) 0 +#define paranoid_check_ec_hdr(ubi, pnum, ec_hdr) 0 +#define paranoid_check_peb_vid_hdr(ubi, pnum) 0 +#define paranoid_check_vid_hdr(ubi, pnum, vid_hdr) 0 +#define paranoid_check_all_ff(ubi, pnum, offset, len) 0 +#endif + +/** + * ubi_io_read - read data from a physical eraseblock. + * @ubi: UBI device description object + * @buf: buffer where to store the read data + * @pnum: physical eraseblock number to read from + * @offset: offset within the physical eraseblock from where to read + * @len: how many bytes to read + * + * This function reads data from offset @offset of physical eraseblock @pnum + * and stores the read data in the @buf buffer.

When one creates an UBI image which will be + * flashed to the end devices in production, he does not know the exact amount + * of good physical eraseblocks the NAND chip on the device will have, but this + * number is required to calculate the volume sized and put them to the volume + * table of the UBI image. In this case, one of the volumes (e.g., the one + * which will store the root file system) is marked as "auto-resizable", and + * UBI will adjust its size on the first boot if needed. + * + * Note, first UBI reserves some amount of physical eraseblocks for bad + * eraseblock handling, and then re-sizes the volume, not vice-versa.

The volume table is an + * on-flash table containing volume meta-data like name, number of reserved + * physical eraseblocks, type, etc. The volume table is stored in the so-called + * "layout volume". + * + * The layout volume is an internal volume which is organized as follows. It + * consists of two logical eraseblocks - LEB 0 and LEB 1. Each logical + * eraseblock stores one volume table copy, i.e. LEB 0 and LEB 1 duplicate each + * other. This redundancy guarantees robustness to unclean reboots. The volume + * table is basically an array of volume table records. Each record contains + * full information about the volume and protected by a CRC checksum. + * + * The volume table is changed, it is first changed in RAM. Then LEB 0 is + * erased, and the updated volume table is written back to LEB 0. Then same for + * LEB 1. This scheme guarantees recoverability from unclean reboots. + * + * In this UBI implementation the on-flash volume table does not contain any + * information about how many data static volumes contain. This information may + * be found from the scanning data. + * + * But it would still be beneficial to store this information in the volume + * table. For example, suppose we have a static volume X, and all its physical + * eraseblocks became bad for some reasons. Suppose we are attaching the + * corresponding MTD device, the scanning has found no logical eraseblocks + * corresponding to the volume X. According to the volume table volume X does + * exist. So we don't know whether it is just empty or all its physical + * eraseblocks went bad. So we cannot alarm the user about this corruption. + * + * The volume table also stores so-called "update marker", which is used for + * volume updates. Before updating the volume, the update marker is set, and + * after the update operation is finished, the update marker is cleared.

It works in terms of physical + * eraseblocks and erase counters and knows nothing about logical eraseblocks, + * volumes, etc. From this unit's perspective all physical eraseblocks are of + * two types - used and free. Used physical eraseblocks are those that were + * "get" by the 'ubi_wl_get_peb()' function, and free physical eraseblocks are + * those that were put by the 'ubi_wl_put_peb()' function. + * + * Physical eraseblocks returned by 'ubi_wl_get_peb()' have only erase counter + * header. The rest of the physical eraseblock contains only 0xFF bytes. + * + * When physical eraseblocks are returned to the WL unit by means of the + * 'ubi_wl_put_peb()' function, they are scheduled for erasure. The erasure is + * done asynchronously in context of the per-UBI device background thread, + * which is also managed by the WL unit. + * + * The wear-leveling is ensured by means of moving the contents of used + * physical eraseblocks with low erase counter to free physical eraseblocks + * with high erase counter. + * + * The 'ubi_wl_get_peb()' function accepts data type hints which help to pick + * an "optimal" physical eraseblock. For example, when it is known that the + * physical eraseblock will be "put" soon because it contains short-term data, + * the WL unit may pick a free physical eraseblock with low erase counter, and + * so forth. + * + * If the WL unit fails to erase a physical eraseblock, it marks it as bad. + * + * This unit is also responsible for scrubbing.
