2013-03-08omap3: allow dynamic selection of gfx_formatNikita Kiryanov
Currently, omap3_dss_panel_config() sets gfx_format to a value that is hardcoded in the code. This forces anyone who wants to use a different gfx_format to make adjustments after calling omap3_dss_panel_config(). This could be avoided if the value of gfx_format were parameterized as input for omap3_dss_panel_config(). Make gfx_format a field in struct panel_config, and update existing structs to set this field to the value that was originally hard coded.

2013-03-07mxs: mmc: spi: dma: Better wrap the MXS differencesMarek Vasut
This patch streamlines the differences between the MX23 and MX28 by implementing a few helper functions to handle different DMA channel mapping, different clock domain for SSP block and fixes a few minor bugs. First of all, the DMA channel mapping is now fixed in dma.h by defining the actual channel map for both MX23 and MX28. Thus, MX23 now does no longer use MX28 channel map which was wrong. Also, there is a fix for MX28 DMA channel map, where the last four channels were incorrect. Next, because correct DMA channel map is in place, the mxs_dma_init_channel() call now bases the channel ID starting from SSP port #0. This removes the need for DMA channel offset being added and cleans up the code. For the same reason, the SSP0 offset can now be used in mxs_dma_desc_append(), thus no need to adjust dma channel number in the driver either. Lastly, the SSP clock ID is now retrieved by calling mxs_ssp_clock_by_bus() which handles the fact that MX23 has shared SSP clock for both ports, while MX28 has per-port SSP clock. Finally, the mxs_ssp_bus_id_valid() pulls out two implementations of the same functionality from MMC and SPI driver into common code.

2013-03-07mxs: Reset the EMI block on mx23Marek Vasut
The real reason for memory instability was the fact that the EMI block was gated and not reset throughout the boards' operation. This patch resets the EMI block properly while also reverts the memory voltage bump. The memory stability issues were caused by the EMI not being reset properly and thus there is no longer need to run the memory at higher voltage than it ought to run at. This partly reverts 8303ed128a55519f19c5f11087032d4bc4e0537a .

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: 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.

2013-02-28sandbox: Add un/map_sysmen() to deal with sandbox's ram_bufSimon Glass
Sandbox doesn't actually provide U-Boot access to the machine's physical memory. Instead it provides a RAM buffer of configurable size, and all memory accesses are within that buffer. Sandbox memory starts at 0 and is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer might produce unpredictable results in the event of an error, and would expose the host machine's memory architecture to the sandbox U-Boot. Most U-Boot functions assume that they can just access memory at given address. For sandbox this is not true. Add a map_sysmem() call which converts a U-Boot address to a system address. In most cases this is a NOP, but for sandbox it returns a pointer to that memory inside the RAM buffer. To get a U-Boot feature to work correctly within sandbox, you should call map_sysmem() to get a pointer to the address, and then use that address for any U-Boot memory accesses.
