* gpio: Add support for microblaze xilinx GPIOMichal Simek2013-05-09-33/+7
| | | | | | | | | | | | | | | | | | | | | | | | Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it. Add gpio driver and change Microblaze reset logic to be done via gpio subsystem. There are various configurations which Microblaze can have that's why gpio_alloc/gpio_alloc_dual(for dual channel) function has been introduced and gpio can be allocated dynamically. Adding several gpios IP is also possible and supported. For listing gpio configuration please use "gpio status" command This patch also remove one compilation warning: microblaze-generic.c: In function 'do_reset': microblaze-generic.c:38:47: warning: operation on '*1073741824u' may be undefined [-Wsequence-point] Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* sandbox: Provide a way to map from host RAM to U-Boot RAMSimon Glass2013-05-01-0/+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>

| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
