* ARM: tegra: Make cache line size SoC specificThierry Reding2013-08-19-0/+3
| | | | | | | | | | | | Currently all Tegra SoCs are assumed to have 32 byte cache lines. This isn't true for Tegra114, however, which uses 4 Cortex-A15 cores and therefore uses a cache line size of 64 bytes. Move the cache line size setting to the per-SoC common configuration file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable a common set of partition types, filesystems, and related commands in tegra-common.h, so that they are available on all Tegra boards. This allows boot.scr (loaded and executed by the default built-in environment) on those boards to assume that certain features are always available. Do this in tegra-common.h, so that individual board files can undefine the features if they really don't want any of them.

* | ARM: tegra: enable some CPU errata workaroundsStephen Warren2013-03-13-0/+6
|/ | | | | | | | | | | | Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such, some CPU errata exist, and must be worked around. These must be worked around in the bootloader, since in general, the kernel (especially a multi-platform kernel) needs to support being launched in non-secure mode (normal world), and hence may not be able to write to the CP15 register to enable these workarounds.

| * mmc: tegra: use bounce buffer APIsStephen Warren2012-11-27-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ARM: tegra: derive CONFIG_SPL_MAX_SIZE instead of hard-coding itStephen Warren2012-10-29-1/+2
| | | | | | | | | | | | | | | For Tegra, the SPL and main U-Boot are concatenated together to form a single memory image. Hence, the maximum SPL size is the different in TEXT_BASE for SPL and main U-Boot. Instead of manually calculating SPL_MAX_SIZE based on those two TEXT_BASE, which can lead to errors if one TEXT_BASE is changed without updating SPL_MAX_SIZE, simply perform the calculation automatically.

* ARM: tegra: define CONFIG_SYS_BOOTMAPSZStephen Warren2012-10-29-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This define indicates the size of the memory region where it is safe to place data passed to the Linux kernel (ATAGs, DTB, initrd). The value needs to be: a) Less than or equal to RAM size. b) Small enough that the area is not within the kernel's highmem region, since the kernel cannot access ATAGs/DTB/initrd from highmem. c) Large enough to hold the kernel+DTB+initrd. 256M seems large enough for (c) in most circumstances, and small enough to satisfy (a) and (b) across any possible Tegra board. Note that the user can override this value via environment variable "bootm_mapsize" if needed. The advantage of defining BOOTMAPSZ is that we no longer need to define variable fdt_high in the default environment. Previously, we defined this to prevent the DTB from being relocated to the very end of RAM, which on most Tegra systems is within highmem, and hence which would cause boot failures. A user can still define this variable themselves if they want the FDT to be either left in-place wherever loaded, or copied to some other specific location. Similarly, there should no longer be a strict requirement for the user to define initrd_high if using an initrd.

| | | | | | | | | | | The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.
