2012-12-13env: Hide '.' variables in env print by defaultJoe Hershberger
When printing all variables with env print, don't print variables that begin with '.'. If env print is called with a '-a' switch, then include variables that begin with '.' (just like the ls command). Variables printed explicitly will be printed even without the -a. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-12-13env: Use getenv_yesno() more generallyJoe Hershberger
Move the getenv_yesno() to env_common.c and change most checks for 'y' or 'n' to use this helper. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-12-13env: Refactor apply into change_okJoe Hershberger
Move the read of the old value to inside the check function. In some cases it can be avoided all together and at the least the code is only called from one place. Also name the function and the callback to more clearly describe what it does. Pass the ENTRY instead of just the name for direct access to the whole data structure. Pass an enum to the callback that specifies the operation being approved. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-12-13env: Refactor do_apply to a flagJoe Hershberger
Use a flag in hsearch_r for insert mode passed from import to allow the behavior be different based on use. Now that "do_check" is called for all imports, ensure console init is complete before updating the console on relocation import Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-12-13Make linux kernel string funcs available to toolsJoe Hershberger
isspace() and strim() are not in the typical user-mode string.h, so put them in a separate compilation unit so that they can be built into tools that need them independent of the other common string functions. This allows code shared by u-boot and the linux user-mode tools to link. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

This implements a library for accessing EDID data from an LCD panel. This is used to obtain information about the panel such as its resolution and type. This is a tidied-up version of the original code pulled from https://github.com/ynezz/u-boot-edid. The changes we made are: - removed bit fields in the struct; - removed endianness cases in the struct; - fixed some wrong definitions; - fixed to fit 80 columns; - fixed some code styles.

2012-12-11Add hash command to perform hashing using various algorithmsSimon Glass
This new command supports hashing SHA1 and SHA256. It could be extended to others such as MD5 and the CRC algorithms. The syntax is modeled on those: hash <algorithm> <address> <length> [*<dest_addr> | <dest_envvar>] to calculate a hash, and: hash -v <algorithm> <address> <length> [*<verify_addr> | <verify_envvar>] to verify a hash. Use CONFIG_CMD_HASH to enable the command, CONFIG_SHA1 to enable SHA1 and CONFIG_SHA256 to enable SHA256. The existing sha1sum command remains. Signed-off-by: Simon Glass <sjg@chromium.org>

2012-12-11Add strcasecmp() and strncasecmp()Simon Glass
strncasecmp() is present as strnicmp() but disabled. Make it available and define strcasecmp() also. There is a only a small performance penalty to having strcasecmp() call strncasecmp(), so do this instead of a standalone function, to save code space.

2012-11-30x86: Add CBMEM console driver for corebootVadim Bendebury
This patch builds upon the recently introduced CBMEM console feature of coreboot. CBMEM console uses a memry area allocated by coreboot to store the console output. The memory area has a certain structure, which allows to determine where the buffer is, the buffer size and the location of the pointer in the buffer. This allows different phases of the firmware (rom based coreboot, ram based coreboot, u-boot after relocation with this change) to keep adding text to the same buffer. Note that this patch introduces a new console driver and adds the driver to the list of drivers to be used for console output, i.e. it engages only after u-boot relocates. Usiong CBMEM console for capturing the pre-relocation console output will be done under a separate change. >From Linux, run the cbmem.py utility (which is a part of the coreboot package) to see the output, e.g.: vvvvvvvvvvvvvvvvv SCSI: AHCI 0001.0300 32 slots 6 ports ?

Magic signature found Kernel command line: "cros_secure quiet loglevel=1 console=tty2... ^^^^^^^^^^^^^^^^^ Note that the entire u-boot output fits into the buffer only if the coreboot log level is reduced from the most verbose.

2012-11-27mmc: tegra: use bounce buffer APIsStephen Warren
Tegra's MMC driver does DMA, and hence needs cache-aligned buffers. In some cases (e.g. user load commands) this cannot be guaranteed by callers of the MMC APIs. To solve this, modify the Tegra MMC driver to use the new bounce_buffer_*() APIs. Note: Ideally, all U-Boot code will always provide address- and size- aligned buffers, so a bounce buffer will only ever be needed for user- supplied buffers (e.g. load commands). Ensuring this removes the need for performance-sucking bounce buffer cache management and memcpy()s. The one known exception at present is the SCR buffer in sd_change_freq(), which is only 8 bytes long. Solving this requires enhancing struct mmc_data to know the difference between buffer size and transferred data size, or forcing all callers of mmc_send_cmd() to have allocated buffers using ALLOC_CACHE_ALIGN_BUFFER(), which while true in this case, is not enforced in any way at present, and so cannot be assumed by the core MMC code.
