* a4m072: led display supportIlya Yanok2010-10-12-2/+184
| | | | | | | | This patch adds support for LED display on a4m072 board. Hardware is capable of displaying only one symbol at any time. We support displaying two symbols in software (via blinking). Signed-off-by: Ilya Yanok <yanok@emcraft.com>
* led_display: split led display support into generic and hw-dependent partsIlya Yanok2010-10-12-17/+136
| | | | | | | | | | | Split the display command into generic interface and hardware-specific realization for PDSP188x LED display found on hmi1001 and manroland boards. Simple interface for LED displays is defined in include/led-display.h and described in doc/README.LED_display. Driver-specific implementation was moved into drivers/misc/pdsp188x.c file (enabled with CONFIG_PDSP188x set). Signed-off-by: Ilya Yanok <yanok@emcraft.com>

* VFAT: fix processing of scattered long file name entriesMikhail Zolotaryov2010-10-12-12/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The U-Boot code has the following bugs related to the processing of Long File Name (LFN) entries scattered across several clusters/sectors : 1) get_vfatname() function is designed to gather scattered LFN entries by cluster chain processing - that doesn't work for FAT12/16 root directory. In other words, the function expects the following input data: 1.1) FAT32 directory (which is cluster chain based); OR 1.2) FAT12/16 non-root directory (which is also cluster chain based); OR 1.3) FAT12/16 root directory (allocated as contiguous sectors area), but all necessary information MUST be within the input buffer of filesystem cluster size (thus cluster-chain jump is never initiated). In order to accomplish the last condition, root directory parsing code in do_fat_read() uses the following trick: read-out cluster-size block, process only first sector (512 bytes), then shift 512 forward, read-out cluster-size block and so on. This works great unless cluster size is equal to 512 bytes (in a case you have a small partition), or long file name entries are scattered across three sectors, see 4) for details. 2) Despite of the fact that get_vfatname() supports FAT32 root directory browsing, do_fat_read() function doesn't send current cluster number correctly, so root directory look-up doesn't work correctly. 3) get_vfatname() doesn't gather scattered entries correctly also is the case when all LFN entries are located at the end of the source cluster, but real directory entry (which must be returned) is at the only beginning of the next one. No error detected, the resulting directory entry returned contains a semi-random information (wrong size, wrong start cluster number and so on) i.e. the entry is not accessible. 4) LFN (VFAT) allows up to 20 entries (slots) each containing 26 bytes (13 UTF-16 code units) to represent a single long file name i.e. up to 520 bytes. U-Boot allocates 256 bytes buffer instead, i.e. 10 or more LFN slots record may cause buffer overflow / memory corruption. Also, it's worth to mention that 20+1 slots occupy 672 bytes space which may take more than one cluster of 512 bytes (medium-size FAT32 or small FAT16 partition) - get_vfatname() function doesn't support such case as well. The patch attached fixes these problems in the following way: - keep using 256 bytes buffer for a long file name, but safely prevent a possible buffer overflow (skip LFN processing, if it contains 10 or more slots). - explicitly specify FAT12/16 root directory parsing buffer size, instead of relying on cluster size. The value used is a double sector size (to store current sector and the next one). This fixes the first problem and increases performance on big FAT12/16 partitions; - send current cluster number (FAT32) to get_vfatname() during root directory processing; - use LFN counter to seek the real directory entry in get_vfatname() - fixes the third problem; - skip deleted entries in the root directory (to prevent bogus buffer overflow detection and LFN counter steps). Note: it's not advised to split up the patch, because a separate part may operate incorrectly. Signed-off-by: Mikhail Zolotaryov <lebon@lebon.org.ua>

* zlib: Add further watchdog reset callsStefan Roese2010-10-12-0/+1
| | | | | | | | | | | | | | | Patch 253cb831 [zlib: add watchdog reset call] added already a few watchdog reset calls to the new zlib U-Boot port. But on some boards this is not enough. Additional calls are needed on boards with short watchdog timeouts. This was detected and tested on the lwmon5 board with a very short watchdog timeout. Without this patch, the board resets during Linux kernel decompression. With it, the decompression succeeds.

* zlib/gunzip: Use WATCHDOG_RESET macroStefan Roese2010-10-12-11/+4
| | | | | | | | | | | | | | | | | | | | | | As usually done in U-Boot, the watchdog_reset code is called via a macro (WATCHDOG_RESET). In zlib.c this was done differently, by using a function pointer which is initialized with WATCHDOG_RESET upon watchdog usage or with NULL otherwise. This patch now uses the plain WATCHDOG_RESET macros to call the function resulting in slightly smaller U-Boot images and simpler code. U-Boot code size reduction: PowerPC board with watchdog support (lwmon5): -> 80 bytes smaller image size PowerPC board without watchdog support (sequoia): -> 112 bytes smaller image size Signed-off-by: Stefan Roese <sr@denx.de> Cc: Detlev Zundel <dzu@denx.de> Cc: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>

All the davinci boards had the behaviour, prior to this patch, of sync'ing the environment variable enetaddr with the MAC address read from non-volatile storage on boot -- when the two locations disagreed, the environment variable value took precendence. This patch keeps the same behaviour but lets eth_initialize take care of it. This patch refactors davinci_emac setup in the boards so that the MAC address is read from non-volatile storage into the environment variable and then the environment variable value is use in eth_intialize. The only exception is the direct call to davinci_eth_set_mac_addr made by the da830evm board init which was changed into an assignment of the enetaddr field.

* | mtdparts: add new sub-command "spread"Ben Gardiner2010-10-11-1/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the 'spread' sub-command of the mtdparts command. This command will modify the existing mtdparts variable by increasing the size of the partitions such that 1) each partition's net size is at least as large as the size specified in the mtdparts variable and 2) each partition starts on a good block. The new subcommand is implemented by iterating over the mtd device partitions and collecting a bad blocks count in each -- including any trailing bad blocks -- and then modifying that partitions's part_info structure and checking if the modification affects the next partition. This patch is based on a port of the 'dynnamic partitions' feature by Harald Welte <laforge@gnumonks.org>; ported from commit e05835df019027391f58f9d8ce5e1257d6924798 of git://git.openmoko.org/u-boot.git.

* | nand erase: .spread, .part, .chip subcommandsScott Wood2010-10-11-22/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A while back, in http://lists.denx.de/pipermail/u-boot/2009-June/054428.html, Michele De Candia posted a patch to not count bad blocks toward the requested size to be erased. This is desireable when you're passing in something like $filesize, but not when you're trying to erase a partition. Thus, a .spread subcommand (named for consistency with http://lists.denx.de/pipermail/u-boot/2010-August/075163.html) is introduced to make explicit the user's desire to erase for a given amount of data, rather than to erase a specific region of the chip. While passing $filesize to "nand erase" is useful, accidentally passing something like $fliesize currently produces quite unpleasant results, as the variable evaluates to nothing and U-Boot assumes that you want to erase the entire rest of the chip/partition. To improve the safety of the erase command, require the user to make explicit their intentions by using a .part or .chip subcommand. This is an incompatible user interface change, but keeping compatibility would eliminate the safety gain, and IMHO it's worth it. While touching nand_erase_opts(), make it accept 64-bit offsets and sizes, fix the percentage display when erase length is rounded up, eliminate an inconsistent warning about rounding up the erase length which only happened when the length was less than one block (rounding up for $filesize is normal operation), and add a diagnostic if there's an attempt to erase beginning at a non-block boundary.

|/ | | | | | | | | | | | | | | | The underlying code in nand_base.c already supports non-page-aligned reads and writes, but the block-skipping wrapper code did not. With block skipping, an unaligned start address is not useful since you really want to be starting at the beginning of a partition -- or at least that's where you want to start checking for blocks to skip, but we don't (yet) support that. So we still require the start address to be aligned. An unaligned length, though, is useful for passing $filesize to the read/write command, and handling it does not complicate block skipping.

| | | | | | | | | | | | | | | | u-boot.bin can be loaded at any 4-byte aligned memory location and directly 'jumped' to using the 'go' command using the load address as the start address. Doing so performs a 'warm boot' which skips memory initialisation and other low-level initialisations, relocates U-Boot to upper memory and starts U-Boot in RAM as per normal 'cold boot'
