* sandbox: Allow -c argument to provide a command listSimon Glass2013-05-011-1/+1
| | | | | | | | This allows passing of entire scripts to sandbox with the -c argument, which is useful for testing. Commands can be delimited with a newline or semicolon. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host fileSimon Glass2013-05-012-0/+8
| | | | | | | | | | | | With sandbox it is tricky to add an FDT to the image at build time (or later) since we build an ELF file, not a plain binary, and the address space of the whole U-Boot is not accessible in the emulated memory map of sandbox. Sandbox can read files directly from the host, though, so add an option to read an FDT from a host file on start-up. Signed-off-by: Simon Glass <sjg@chromium.org>

* sandbox: Provide a way to map from host RAM to U-Boot RAMSimon Glass2013-05-012-0/+8
| | | | | | | | | | | | | | | | | | | | | In many cases, pointers to memory are passed around, and these pointers refer to U-Boot memory, not host memory. This in itself is not a problem. However, in a few places, we cast that pointer back to a ulong (being a U-Boot memory address). It is possible to convert many of these cases to avoid this. However there are data structures (e.g. struct bootm_headers) which use pointers. We could with a lot of effort adjust the structs and all code that uses them to use ulong instead of pointers. This seems like an unacceptable cost, since our objective with sandbox is to minimise the impact on U-Boot code while maximising the features available to sandbox. Therefore, create a map_to_sysmem() function which converts from a pointer to a U-Boot address. This can be used sparingly when needed. Signed-off-by: Simon Glass <sjg@chromium.org>

| * Tegra: Restore cp15 VBAR _start vector write for ARMv7Tom Warren2013-04-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | A start vector fix was added by AneeshV for OMAP4 (commit 0d479b53), and caused the old monilithic Tegra builds to hang due to an undefined instruction trap. Previously, the code needed to run on both the AVP (ARM7TDI) and A9, and the AVP doesn't have a CP15 register. I corrected this in commit 6d6c0bae w/#ifndef CONFIG_TEGRA, but now that we use SPL, and boot the AVP w/o any ARMv7 code, I can revert my change, and make Aneesh's change apply to Tegra.

| * ARM: tegra: support T33 SKU of Tegra30Stephen Warren2013-04-152-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make U-Boot aware of the T33 SKU of Tegra30, and treat it identically to any other Tegra30. An alternative would be to simply remove the SKU checking from tegra_get_chip_type(); most use of the value most likely simply wants to know the current chip, not the specific SKU. Or, the function could be split into separate tegra_get_chip() and tegra_get_sku() for the cases where differentiation really is required. I wonder whether tegra_get_chip_type() should printf() whenever any unkown chip/SKU is found, although perhaps the function is called so early that the printf() wouldn't actually make it to the UART anyway.

| * x86: Fix DRAM bank size init with generic boardSimon Glass2013-04-151-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | The intention of the memory init code is that it should work the same with CONFIG_SYS_GENERIC_BOARD and without. This is tricky because dram_init() is called prior to relocation with generic board (matching other archs) and after relocation without generic board. Adjust the init sequence so that dram_init() is not called in the generic board case, which seems like the easiest fix for now. Also ensure that relocation addresses are still calculated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The glitch in the SPI clock line, which commit 3cea335c34 (spi: mxc_spi: Fix spi clock glitch durant reset) solved, is back now and itwas re-introduced by commit d36b39bf0d (spi: mxc_spi: Fix ECSPI reset handling). Actually the glitch is happening due to always toggling between slave mode and master mode by configuring the CHANNEL_MODE bits in this reset function. Since the spi driver only supports master mode, set the mode for all channels always to master mode in order to have a stable, "glitch-free" SPI clock line.

The wait_ticks function depends on the registers r0, r6 and r7 being preserved however that is not guaranteed, e.g. if the reset function is a C function this will probably overwrite r0 and cause an endless loop. The following patch changes to using r14+r15 instead of r6+r7 (to resemble what would have been generated by a C compiler) and saves all necessary registers on the stack. The patch has been tested on a custom MPC5125 based machine using the 512x powerpc architecture.
