* MIPS: start.S: simplify relocation offset calculationGabor Juhos2013-01-27-18/+6
| | | | | | | | | | | | | | | | | The current code uses four instructions and a temporary register to calculate the relocation offset and to adjust the gp register. The relocation offset can be calculated directly from the CONFIG_SYS_MONITOR_BASE constant and from the destination address. The resulting offset can be used to adjust the gp pointer. This approach makes the code a bit simpler because it needs two instructions only. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>
* MIPS: start.S: save reused arguments earlier in relocate_codeGabor Juhos2013-01-27-4/+6
| | | | | | | | | Save the reused parameters at the beginning of the 'relocate_code' function. This makes the function a bit more readable. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>
* MIPS: start.S: set sp register directlyGabor Juhos2013-01-27-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code uses two instructions to load the stack pointer into the 'sp' register. This results in the following assembly code: 468: 3c088040 lui t0,0x8040 46c: 251d0000 addiu sp,t0,0 The first instuction loads the stack pointer into the 't0' register then the value of the 'sp' register is computed by adding zero to the value of the 't0' register. The same issue present on the 64-bit version as well: 56c: 3c0c8040 lui t0,0x8040 570: 659d0000 daddiu sp,t0,0 Change the code to load the stack pointer directly into the 'sp' register. The generated code is functionally equivalent to the previous version but it is simpler. 32-bit: 468: 3c1d8040 lui sp,0x8040 64-bit: 56c: 3c1d8040 lui sp,0x8040 Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>
* MIPS: start.S: fix boundary check in relocate_codeGabor Juhos2013-01-27-3/+3
| | | | | | | | | | | | | The loop code copies more data with one than necessary due to the 'ble' instuction. Use the 'blt' instruction instead to fix that. Due to the lack of suitable hardware the Xburst specific code is compile tested only. However the change is quite obvious.

* MIPS: start{, 64}.S: fill branch delay slots with NOP instructionsGabor Juhos2013-01-22-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | The romReserved and romExcHandle handlers are accessed by a branch instruction however the delay slots of those instructions are not filled. Because the start.S uses the 'noreorder' directive, the assembler will not fill the delay slots either, and leads to the following assembly code: 0000056c <romReserved>: 56c: 1000ffff b 56c <romReserved> 00000570 <romExcHandle>: 570: 1000ffff b 570 <romExcHandle> In the resulting code, the second branch instruction is placed into the delay slot of the first branch instruction, which is not allowed on the MIPS architecture.

| * | mx6qsabresd: Fix booting the kernel from SDHC3Fabio Estevam2013-01-13-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit de7d02aeb (mx6qsabresd: add usdhc2 and usdhc4 support) SDHC3 device node is no longer 0, which breaks loading a uImage from SDHC3. Fix it by adapting the default environment to use CONFIG_SYS_MMC_ENV_DEV as the correct mmc node for loading the kernel from. While at it, go back to using SDHC3 as the default mmc, since we have Yocto images that generate an SD card containing U-boot,kernel and rootfs, so it is more convenient to keep using SDHC3 as it was originally.

| * | | EXYNOS: Add dummy definition to fix compilation dependency on ↵Ajay Kumar2013-01-10-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_EXYNOS_MIPI_DSIM When only DP is used, we need not enable CONFIG_EXYNOS_MIPI_DSIM. But if we do not select CONFIG_EXYNOS_MIPI_DSIM, exynos_fb.c throws error saying exynos_mipi_dsi_init() not defined. So, we add dummy definition for exynos_mipi_dsi_init when CONFIG_EXYNOS_MIPI_DSIM is not defined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With VPLL as source clock to FIMD, Exynos DP Initializaton was failing sometimes with unstable clock. Changing FIMD source to MPLL resolves this issue.
