* powerpc/85xx:Avoid vector table compilation for nand_splPrabhakar Kushwaha2012-04-24-0/+6
| | | | | | | | NAND SPL code never compile the vector table. So no need to setup interrupt vector table for NAND SPL. Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
* powerpc/85xx:Fix IVORs addr after vector table relocationPrabhakar Kushwaha2012-04-24-0/+33
| | | | | | | | | | | After relocation of vector table in SDRAM's lower address, IVORs value should be updated with new handler addresses. As vector tables are relocated to 0x100,0x200... 0xf00 address in DDR.IVORs are updated with 0x100, 0x200,....f00 hard-coded values.

* powerpc/85xx:Avoid hardcoded vector address for IVORsPrabhakar Kushwaha2012-04-24-31/+34
| | | | | | | | | | | | For e500 and e500v2 architecturees processor IVPR address should be alinged on 64K boundary. in start.S, CONFIG_SYS_MONITOR_BASE is stored blindly in IVPR assuming it to be 64K aligned. It may not be true always. If it is not aligned, IVPR + IVORs may not point to an exception handler.

* DMA: Split the APBH DMA init into block and channel initMarek Vasut2012-04-16-1/+9
| | | | | | | | | | | | | | | | | | | | | | | This fixes the issue where mxs_dma_init() was called either twice or never, without introducing any new init hooks. The idea is to allow each and every device using the APBH DMA block to configure and request only the channels it uses, instead of making it call init for all the channels as is now. The common DMA block init part, which only configures the block, is then called from CPUs arch_cpu_init() call.

* ARM1136: add cache flush and invalidate operationsAnatolij Gustschin2012-04-16-0/+95
| | | | | | | | | | | | | | | | | | Since commit 5c1ad3e6f8ae578bbe30e09652f1531e9bc22031 (net: fec_mxc: allow use with cache enabled) the FEC_MXC driver uses flush_dcache_range() and invalidate_dcache_range() functions. This driver is also configured for ARM1136 based 'flea3' and 'mx35pdk' boards which currently do not build as there are no ARM1136 specific flush_dcache_range() and invalidate_dcache_range() functions. Add various ARM1136 cache functions to fix building for 'flea3' and 'mx35pdk'.

| * | arm: Use common .lds file where possibleSimon Glass2012-03-30-1071/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each cpu directory currently has its own .lds file. This is only needed in most cases because the start.o file is in a different subdir.

| * | arm: add a common .lds link scriptSimon Glass2012-03-30-0/+94

This adds a basic script that can be used by most CPUs. Two new symbols are introduced which are intended to eventually be defined on all architectures to make things easier for generic relocation and reduce special-case code for each architecture: __image_copy_start is the start of the text area (equivalent to the existing _start on ARM). It marks the start of the region which must be copied to a new location during relocation. This symbol is called __text_start on x86 and microblaze. __image_copy_end is the end of the region which must be copied to a new location during relocation. It is normally equal to the start of the BSS region, but this can vary in some cases (SPL?). Making this an explicit symbol on its own removes any ambiguity and permits common code to always do the right thing. This new script makes use of CPUDIR, now defined by both Makefile and spl/Makefile, to find the directory containing the start.o object file, which is always placed first in the image. To permit MMU setup prior to relocation (as used by pxa) we add an area to the link script which contains space for this. This is taken from commit 7f4cfcf. CPUs can put the contents in there using their start.S file. BTW, shouldn't that area be 16KB-aligned? Signed-off-by: Simon Glass <sjg@chromium.org>

| * | tegra: usb: fdt: Add additional device tree definitions for USB portsSimon Glass2012-03-29-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds clock references to the USB part of the device tree for U-Boot, and marks USB1 as supporting legacy mode (which we disable in the driver). The USB timing information may vary between boards sometimes, but for now we hard-code it in C. This is because all current T2x boards use the same values, we will deal with T3x later and we first need to agree on the format for this timing information in the fdt and may in fact decide that it has no place there.

| * | tegra: fdt: Add clock bindingsSimon Glass2012-03-29-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a basic binding for the oscillator and peripheral clocks. The second cell is the clock number, defined as the bit number within the clock enable register if the peripheral clock. This uses the RFC clock bindings from Grant Likely so may change later: https://lkml.org/lkml/2011/12/12/498 It is taken from Stephen Warren's patch here: http://patchwork.ozlabs.org/patch/141359/ Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

| * | arm: Tegra2: Fix ELDK42 gcc failure with inline asm stack pointer loadTom Warren2012-03-29-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 4.2.2 gcc in the ELDK42 release doesn't like the direct SP load using a constant in tegra2_start. Change it to use a load thru another reg using mov sp, %0 : : "r"(CONST). Tested on my Seaboard T20-A03, U-Boot loads and runs OK. Also compiled all tegra2 builds with both gcc 4.2.2 and 4.4.1 OK.
