Malloc pool size of 1MiB was too small, since we needed bigger buffer to transfer for example uImage.

| | * | EXYNOS: Move files from board/samsung to arch/armRajeshwari Shinde2013-07-05-4/+19

Converted the common lowlevel_init from assembly to C-code 4) Made spl_boot.c and tzpc_init.c common for both exynos4 and exynos5. 5) Enable CONFIG_SKIP_LOWLEVEL_INIT as stack pointer initialisation is already done in _main. 6) exynos-uboot-spl.lds made common across SMDKV310, Origen and SMDK5250. TEST: Tested SD-MMC boot on SMDK5250 and Origen. Tested USB and SPI boot on SMDK5250 Compile tested for SMDKV310.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Exynos5250 silicon may require 1.05v on the MIF to be stable, so to be safe we can default to 1.05v instead of 1.00v. This can be set optimally later in the boot process by the kernel. The 0x6 value for 1.05v comes from the MAX77686 datasheet.

A quick overview of u-boot implementation on the treo 680... The treo 680 has a Diskonchip G4 nand flash chip. This device has a 2k region that maps to the system bus at the reset vector in a NOR-like fashion so that it can be used as the boot device. The phone is shipped with this 2k region configured as write-protected (can't be modified) and programmed with an initial program loader (IPL). At power-up, this IPL loads the contents of two flash blocks to SDRAM and jumps to it. The capacity of the two blocks is not large enough to hold all of u-boot, so a u-boot SPL is used. To conserve flash space, these two blocks and the necessary number of subsequent blocks are programmed with a concatenated spl + u-boot image. That way, the IPL will also load a portion of u-boot proper, and when the spl runs, it relocates the portion of u-boot that the IPL has already loaded, and then resumes loading the remaining part of u-boot before jumping to it. The default_environment is used (CONFIG_ENV_IS_NOWHERE) because I didn't think that having a writable environment was worth the cost of a flash block, although adding it would be straightforward. I abuse the CONFIG_EXTRA_ENV_SETTINGS option to specify the usbtty for the console (CONFIG_SYS_CONSOLE_IS_IN_ENV). Support for the LCD is included, but currently it is only useful for displaying the u-boot splash screen. But if u-boot is built without the usbtty console, it does display the auto-boot progress nicely. Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
* | | | bootm: Use selected configuration for ramdisk and fdtSimon Glass2013-07-12-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a specific configuraion is selected by the bootm command, e.g. with 'bootm 84000000#recoveryconf' we must honour this for not just the kernel, but also the ramdisk and FDT. In the conversion to using a common fit_image_load() function for loading images from FITs (commits a51ec63 and 53f375f) this feature was lost. Reinstate it by passing the selected configuration back from fit_image_load() to boot_get_kernel(), then use this configuration (which is stored in images->fit_uname_cfg) in both boot_get_ramdisk() and boot_get_fdt().

For some obscure reason, the current U-Boot code uses lbaint_t for the number of blocks to read (a rather optimistic estimation of how RAM sizes will evolve), but not for the starting address. Trying to access blocks beyond the 2TiB boundary will simply wrap around and read a block within the 0..2TiB range. We now use lbaint_t for block start addresses, too. This required changes to all block drivers as the signature of block_read(), block_write() and block_erase() in block_dev_desc_t changed. Signed-off-by: Sascha Silbe <t-uboot@infra-silbe.de>

Images are signed using a private key by mkimage. Then at run-time, the images are verified using a private key. This implementation uses openssl for the host part (mkimage).

Quite a bit of work happens in bootm, and we don't want to have to stop tracing before bootm starts.

This makes the code harder to maintain and means that changes must be made to several places. Introduce do_bootm_states() which performs selected portions of the bootm work, so that both plain 'bootm' and 'bootm <sub_command>' can use the same code. Additional duplication exists in bootz, so tidy that up as well. This is not intended to change behaviour, apart from minor fixes where the previously-duplicated code missed some chunks of code.

* | | | | sandbox: Support trace featureSimon Glass2013-06-26-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support tracing on sandbox by adding suitable CONFIG options. To enable it, compile U-Boot with FTRACE=1. The timer functions are marked to skip tracing, since these are called from the tracing code itself, and we want to avoid an infinite loop.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add hooks for tracing to generic board, including: - allow early tracing to start early as possible in U-Boot - reserve memory for trace buffer - copy early trace buffer to main trace buffer after relocation - setup full tracing support after relocation Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a library which supports tracing of execution using built-in gcc features and a microsecond timer. This can be used to record a list of function which are executed, along with a timestamp for each. Later this information can be sent to the host for processing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I am not sure of the meaning of extern inline, but this gives errors when building with function instrumenting enabled. Change these functions to static inline. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch initiates cros-ec in board_init() to enable it for smdk5250. This patch depends on the patch in the MMC series that brings in exynos5-dt.c. Refer to http://patchwork.ozlabs.org/patch/240084.
