| | | | | | | | | | | | | | | | | | | | | | | | | | Add basic i2c driver for Tegra2 with 8- and 16-bit address support.

* | fdt: Add function to allow aliases to refer to multiple nodesSimon Glass2012-03-29-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices can deal with multiple compatible properties. The devices need to know which nodes to bind to which features. For example an I2C driver which supports two different controller types will want to know which type it is dealing with in each case. The new fdtdec_add_aliases_for_id() function deals with this by allowing the driver to search for additional compatible nodes for a different ID. It can then detect the new ones and perform appropriate processing. Another option considered was to return a tuple (node offset, compat id) and have the function be passed a list of compatible IDs. This is more overhead for the common case though. We may add such a function later if more drivers in U-Boot require it.

* | fdt: Avoid early panic() when there is no FDT presentSimon Glass2012-03-29-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | CONFIG_OF_CONTROL requires a valid device tree. However, we cannot call panic() before the console is set up since the message does not appear, and we get a silent failure. Remove the panic from fdtdec_check_fdt() and provide a new function to prepare the fdt for use. This will be called after the console is ready.

* | fdt: Add basic support for decoding GPIO definitionsSimon Glass2012-03-29-0/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds some support into fdtdec for reading GPIO definitions from the fdt. We permit up to FDT_GPIO_MAX GPIOs in the system. Each GPIO is of the form: gpio-function-name = <phandle gpio_num flags>; where: phandle is a pointer to the GPIO node gpio_num is the number of the GPIO (0 to 223) flags is a flag, as follows: bit meaning 0 0=polarity normal, 1=active low (inverted) An example is: enable-propounder-gpios = <&gpio 43 0>; which means that GPIO 43 is used to enable the propounder (setting the GPIO high), or that you can detect that the propounder is enabled by checking if the GPIO is high (the fdt does not indicate input/output). Two main functions are provided: fdtdec_decode_gpio() reads a GPIO property from an fdt node and decodes it into a structure. fdtdec_setup_gpio() sets up the GPIO by calling gpio_request for you. Both functions can cope with the property being missing, which is taken to mean that that GPIO function is not available or is not needed. [For reference, from Stephen Warren <swarren@nvidia.com>. It may be that we add this extra complexity later if needed: The correct way to parse such a GPIO property in general is: * Read the first cell. * Find the node referenced by the phandle (the controller). * Ensure property gpio-controller is present in the controller node. * Read property #gpio-cells from the controller node. * Extract #gpio-cells from the original property. * Keep processing more cells from the original property; there may be multiple GPIOs listed. According to the binding documentation in the Linux kernel, Samsung Exynos4 doesn't use this format, and while all other chips do have a flags cell, about 50% of the controllers indicate the cell is unused. ] Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

* | fdt: Tidy up a few fdtdec problemsSimon Glass2012-03-29-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes five trivial issues in fdtdec.c: 1. fdtdec_get_is_enabled() doesn't really need a default value 2. The fdt must be word-aligned, since otherwise it will fail on ARM 3. The compat_names[] array is missing its first element. This is needed only because the first fdt_compat_id is defined to be invalid. 4. Added a header prototype for fdtdec_next_compatible() 5. Change fdtdec_next_alias() to only increment its 'upto' parameter on success, to make the display error messages in the caller easier.

| | | | | | | | | | | | | | | | | | | | | | | | The fdtdec_find_aliases_for_id() function is complicated enough that it really should have some tests.

* | fdt: Add fdtdec_find_aliases() to deal with alias nodesSimon Glass2012-03-29-0/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stephen Warren pointed out that we should use nodes whether or not they have an alias in the /aliases section. The aliases section specifies the order so far as it can, but is not essential. Operating without alisses is useful when the enumerated order of nodes does not matter (admittedly rare in U-Boot). This is considerably more complex, and it is important to keep this complexity out of driver code. This patch creates a function fdtdec_find_aliases() which returns an ordered list of node offsets for a particular compatible ID, taking account of alias nodes.

* fdt: add decode helper librarySimon Glass2011-10-26-0/+148
| | | | | | | | | | | | | | | | | | This library provides useful functions to drivers which want to use the fdt to control their operation. Functions are provided to: - look up and enumerate a device type (for example assigning i2c bus 0, i2c bus 1, etc.) - decode basic types from the fdt, like addresses and integers While this library is not strictly necessary, it helps to minimise the changes to a driver, in order to make it work under fdt control. Less code is required, and so the barrier to switch drivers over is lower. Additional functions to read arrays and GPIOs could be made available here also.

* zlib: handle overflow while calculating available stream input sizeAnatolij Gustschin2011-10-17-0/+8
| | | | | | | | | | | | | | | | | | | | | If compressed data is located in sectors at the end of the flash and it's offset + input stream size > 0xFFFFFFFF, the uncompressing time is very long, since processing of the stream is done bytewise (and not blockwise) due to overflow in inflate_fast() while calculation and checking for enough input available. Check for this overflow condition and limit the available stream input size to the actually max. possible input size. This fixes the problem. The issue is easily reproduceable by placing a gziped bitmap in flash, e.g. at FFF80000, and running 'bmp' commands like 'bmp info FFF80000' or 'bmp display FFF80000'. The uncompressing can take up to 3 sec. whereas it should normaly take a fraction of a second. If the 'splashimage' environment variable points to this address, the booting time also increases significantly. Signed-off-by: Anatolij Gustschin <agust@denx.de>

* Add assert() for debug assertionsSimon Glass2011-09-10-5/+8
| | | | | | | | | | | | | | | assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined. This is useful when a condition is an error but a board reset is unlikely to fix it, so it is better to soldier on in hope. Assertion failures should be caught during development/test. It turns out that assert() is defined separately in a few places in U-Boot with various meanings. This patch cleans up some of these.

* libfdt: Implement property iteration functionsDavid Gibson2011-07-14-36/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | For ages, we've been talking about adding functions to libfdt to allow iteration through properties. So, finally, here are some. I got bogged down on this for a long time because I didn't want to expose offsets directly to properties to the callers. But without that, attempting to make reasonable iteration functions just became horrible. So eventually, I settled on an interface which does now expose property offsets. fdt_first_property_offset() and fdt_next_property_offset() are used to step through the offsets of the properties starting from a particularly node offset. The details of the property at each offset can then be retrieved with either fdt_get_property_by_offset() or fdt_getprop_by_offset() which have interfaces similar to fdt_get_property() and fdt_getprop() respectively. No explicit testcases are included, but we do use the new functions to reimplement the existing fdt_get_property() function.

* Support ePAPR compliant phandle propertiesDavid Gibson2011-07-14-6/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the Linux kernel, libfdt and dtc, when using flattened device trees encode a node's phandle into a property named "linux,phandle". The ePAPR specification, however - aiming as it is to not be a Linux specific spec - requires that phandles be encoded in a property named simply "phandle". This patch adds support for this newer approach to dtc and libfdt. Specifically: - fdt_get_phandle() will now return the correct phandle if it is supplied in either of these properties - fdt_node_offset_by_phandle() will correctly find a node with the given phandle encoded in either property. - By default, when auto-generating phandles, dtc will encode it into both properties for maximum compatibility. A new -H option allows either only old-style or only new-style properties to be generated. - If phandle properties are explicitly supplied in the dts file, dtc will not auto-generate ones in the alternate format. - If both properties are supplied, dtc will check that they have the same value. - Some existing testcases are updated to use a mix of old and new-style phandles, partially testing the changes. - A new phandle_format test further tests the libfdt support, and the -H option.

| | | | | | | | | | | | | | | | | | While looking to upgrade to zlib-1.2.5, the current mondo merge of multiple files into a single was making things way more difficult than it should have been. Hard to pick out what has been changed to port it to U-Boot, been removed as useless, and bug fixes added after the fact. So split the single file up into the original file names, and merge non-essential changes back from the original tree (for some reason, style in code in a bunch of places was changed to U-Boot style even though this isn't "U-Boot" code). The original build style is retained -- we have a single zlib.c that includes all the other files, and that is the only file we compile. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

The grepenv command this patch adds can be used in lieu of printenv to facilitate searching. grepenv works like printenv but limits its output only to environment strings (variable name and value pairs) that match the user specified substring. the following examples are on a board with a 5313 byte environment that spans multiple screen pages: Example 1: summarize ethernet configuration: => grepenv eth TSEC etact=FM1@DTSEC2 eth=FM1@DTSEC4 ethact=FM1@DTSEC2 eth1addr=00:E0:0C:00:8b:01 eth2addr=00:E0:0C:00:8b:02 eth3addr=00:E0:0C:00:8b:03 eth4addr=00:E0:0C:00:8b:04 eth5addr=00:E0:0C:00:8b:05 eth6addr=00:E0:0C:00:8b:06 eth7addr=00:E0:0C:00:8b:07 eth8addr=00:E0:0C:00:8b:08 eth9addr=00:E0:0C:00:8b:09 ethaddr=00:E0:0C:00:8b:00 netdev=eth0 uprcw=setenv ethact $eth;setenv filename p4080ds/R_PPSXX_0xe/rcw_0xe_2sgmii_rev2_high.bin;setenv start 0xe8000000;protect off all;run upimage;protect on all upuboot=setenv ethact $eth;setenv filename u-boot.bin;setenv start eff80000;protect off all;run upimage;protect on all upucode=setenv ethact $eth;setenv filename fsl_fman_ucode_P4080_101_6.bin;setenv start 0xef000000;protect off all;run upimage;protect on all usdboot=setenv ethact $eth;tftp 1000000 $dir/$bootfile;tftp 2000000 $dir/initramfs.cpio.gz.uboot;tftp c00000 $dir/p4080ds-usdpaa.dtb;setenv bootargs root=/dev/ram rw console=ttyS0,115200 $othbootargs;bootm 1000000 2000000 c00000; => Example 2: detect unused env vars: => grepenv etact etact=FM1@DTSEC2 => Example 3: reveal hardcoded variables; e.g., for fdtaddr: => grepenv fdtaddr fdtaddr=c00000 nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=$consoledev,$baudrate $othbootargs;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr - $fdtaddr ramboot=setenv bootargs root=/dev/ram rw console=$consoledev,$baudrate $othbootargs;tftp $ramdiskaddr $ramdiskfile;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr $ramdiskaddr $fdtaddr => grep $fdtaddr fdtaddr=c00000 my_boot=bootm 0x40000000 0x41000000 0x00c00000 my_dtb=tftp 0x00c00000 $prefix/p4080ds.dtb nohvboot=tftp 1000000 $dir/$bootfile;tftp 2000000 $dir/$ramdiskfile;tftp c00000 $dir/$fdtfile;setenv bootargs root=/dev/ram rw ramdisk_size=0x10000000 console=ttyS0,115200;bootm 1000000 2000000 c00000; => This patch also enables the grepenv command by default on corenet_ds based boards (and repositions the DHCP command entry to keep the list sorted).

* env: fix env var autocompletionKim Phillips2011-04-28-1/+1
| | | | | | | | | | | | | | | | commit 560d424b6d7cd4205b062ad95f1b104bd4f8bcc3 "env: re-add support for auto-completion" fell short of its description - the 'used' logic in hmatch_r was reversed - 'used' is 0 if the hash table entry is not used, or -1 if deleted. This patch makes hmatch_r actually match on valid ('used') entries, instead of skipping them and failing to match anything. typing 'printenv tft' and hitting 'tab' now displays valid choices for variable names.

* Fix hash table deletion to prevent lost entriesPeter Barada2011-03-22-5/+13
| | | | | | | | | | | | | | Use negative used value to mark deleted entry. Search keeps probing past deleted entries. Adding an entry uses first deleted entry when it hits end of probe chain. Initially found that "ramdiskimage" and "preboot" collide modulus 347, causing "preboot" to be inserted at idx 190, "ramdiskimage" at idx 191. Previous to this fix when "preboot" is deleted, "ramdiskimage" is orphaned. Signed-off-by: Peter Barada <peter.barada@logicpd.com> Tested-by: Wolfgang Denk <wd@denx.de>
