2013-03-08omap_hsmmc: implement driver check for card detectionNikita Kiryanov
Implement driver check for card detection. Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il> Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>
2013-03-08omap_hsmmc: introduce omap_hsmmc_data structNikita Kiryanov
Currently there's no appropriate place to store driver specific data because the pointer that is meant for that (priv) is being used to store the base address of mmc registers. Introduce a new struct for storing driver specific data. Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il>
2013-03-08omap_hsmmc: fix out of bounds array accessNikita Kiryanov
There are 3 MMC/SD/SDIO controllers in OMAP SoCs, but only 2 structs are defined for devices. This leads to data being written outside of array bounds on systems that use all 3 controllers. Update hsmmc_dev array to the correct size. Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il>
2013-03-08omap: consolidate common mmc definitionsNikita Kiryanov
The various mmc_host_def.h files are almost identical. Reduce code duplication by moving the similar definitions to a common header file. Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il> Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>
2013-03-08am33xx: Update DDR3 EMIF configuration sequenceTom Rini
Based on http://processors.wiki.ti.com/index.php/AM335x_EMIF_Configuration_tips we need to re-work our sequence in config_sdram slightly to match what the TRM describes as the correct sequence. In our current (incorrect) sequence some edge cases may fail to initalize correctly. Signed-off-by: Tom Rini <trini@ti.com>
2013-03-08am335x_evm: Add am335x_evm_usbspl build targetTom Rini
We add USB (RNDIS gadget) SPL support as a separate target. We need to pull out YMODEM support in order to be a small enough target binary. Signed-off-by: Tom Rini <trini@ti.com>
2013-03-08am335x_evm: Never set CONFIG_EXTRA_ENV_SETTINGS in SPLTom Rini
Because of our support for network-based SPL, we don't discard all of the environment related functions. We however never make use of the default CONFIG_EXTRA_ENV_SETTINGS items and as this variable grows, it brings us closer to (or with some toolchains, over) our SPL size limit. Never set this in the case of SPL. Signed-off-by: Tom Rini <trini@ti.com>
2013-03-04x86: Enable CONFIG_OF_CONTROL on corebootSimon Glass
Make use of a device tree on coreboot boards, and set the default to link. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-04x86: Adjust link device tree include fileSimon Glass
This is currently set to coreboot.dtsi, but we cannot support this on old device tree compilers (dtc <= 1.3), so adjust to use ARCH_CPU_DTS to let the Makefile preprocessor sort this out. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-04x86: Add error checking to x86 relocation codeSimon Glass
This does not actually change normal behaviour, but adds a check that should detect corruption of relocation data (e.g. by using BSS data prior to relocation). Also add additional debugging output when enabled. During this investigation, two situations have been seen: 1. calculate_relocation_address(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; turns into 111166f: b8 83 c4 17 01 mov $0x117c483,%eax whih is beyond the end of bss: 0117b484 g .bss 00000000 __bss_end Somehow the __bss_end here is 255 bytes ahead. 2. do_elf_reloc_fixups(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; Here the __text_start is 0 in the file: 1111d9f: bb a0 e0 13 01 mov $0x113e0a0,%ebx 1111da4: 81 ef 00 00 00 00 sub $0x0,%edi As it happens, both of these are in pre-relocation code. For these reasons we silent check and ignore bad relocations. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-04x86: Support relocation of FDT on start-upSimon Glass
With CONFIG_OF_CONTROL we may have an FDT in the BSS region. Relocate it up with the rest of U-Boot to keep the rest of memory free. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-04x86: Rearrange the output input to remove BSSSimon Glass
At present BSS data is including in the image, which wastes binary space. Remove it by rearranging the sections so that BSS is last. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-04x86: Add an __end symbol to signal the end of the U-Boot binarySimon Glass
With this symbol we can easy append something (e.g. an FDT) to the U-Boot binary and access it from within U-Boot. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-04x86: Permit bootstage and timer data to be used prior to relocationSimon Glass
It is useful to be able to access the timer before U-Boot has relocated so that we can fully support bootstage. Add new global_data members to support this. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-04x86: Add basic cache operationsSimon Glass
At present most x86 cache operations are undefined. Add a basic implementation for these. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-04x86: Add function to get top of usable ramSimon Glass
The memory layout calculations are done in calculate_relocation_address(), and coreboot has its own version of this function. But in fact all we really need is to set the top of usable RAM, and then the base version will work as is. So instead of allowing the whole calculate_relocation_address() function to be replaced, create board_get_usable_ram_top() which can be used by a board to specify the top of the area where U-Boot relocations to.

2013-03-04bootm: fix conditional compilation for bootm ramdisk subcommandDaniel Schwierzeck
All code related to the bootm ramdisk subcommand is conditionally enabled by CONFIG_SYS_BOOT_RAMDISK_HIGH except for the help message. Replace the CONFIG_ARCH defines by CONFIG_SYS_BOOT_RAMDISK_HIGH to fix this. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2013-03-04env: Avoid clobbering an edited variable on ctrl-cJoe Hershberger

2013-03-04ubifs: Allow ubifsmount volume reference by numberJoe Hershberger
UBI can mount volumes by name or number The current code forces you to name the volume by prepending every name with "ubi:". >From fs/ubifs/super.c * There are several ways to specify UBI volumes when mounting UBIFS: * o ubiX_Y - UBI device number X, volume Y; * o ubiY - UBI device number 0, volume Y; * o ubiX:NAME - mount UBI device X, volume with name NAME; * o ubi:NAME - mount UBI device 0, volume with name NAME. Now any name passed in any of the above forms are allowed. Also update the configs that referenced ubifsmount. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

2013-03-04sandbox: Add 'sb' command to access filesystem featuresSimon Glass
The new 'sb' command is intended to deal with sandbox-specific features that have no parallel in other archs. This commit adds two sub-commands to list a directory and read a file from the host filesystem. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>

2013-03-04sandbox: Add a way of obtaining directory listingsSimon Glass
This implementation uses opendir()/readdir() to access the directory information and then puts it in a linked list for the caller's use. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2013-03-04fs: Move ls and read methods into ext4, fatSimon Glass
It doesn't make a lot of sense to have these methods in fs.c. They are filesystem-specific, not generic code. Add each to the relevant filesystem and remove the associated #ifdefs in fs.c. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2013-03-04fs: Use map_sysmem() on readSimon Glass
This allows us to use filesystems on sandbox. It has no effect on other architectures. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2013-03-04fs: Tell probe functions where to put their resultsSimon Glass
Rather than rely on global variables for the probe functions, pass in the information that we need filled in. This allows us to potentially keep the variables private to fs.c in the future, and the meaning of the probe function is clearer. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2013-03-04fs: Use filesystem methods instead of switch()Simon Glass
We can use the available methods and avoid using switch(). When the filesystem is not supported, we fall through to the 'unsupported' methods: fs_probe_unsupported() prints an error, so the others do not need to. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2013-03-04fs: Fully populate the filesystem method structSimon Glass
There is a structure in fs.c with just a probe method. By adding methods for other operations, we can avoid lots of #ifdefs and switch()s. As a first step, create the structure ready for use. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>

2013-02-28hash: Use lower case for hash algorithm namesSimon Glass
Rather than use strcasecmp() in the hash algorithm search, require the caller to do this first. Most of U-Boot can use lower case anyway, and the hash command can convert to lower case before calling hash_command(). This saves needing strcasecmp() for boards that use hashing but not the hash command. Signed-off-by: Simon Glass <sjg@chromium.org>
