2015-11-12video: mxsfb: introduce lcdif_power_downPeng Fan
Introudce a new function lcdif_power_down. 1. Waits for a VSYNC interrupt to guarantee the reset is done at the VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?) and helps the LCDIF work normally at the kernel stage. 2. Add power down function to stop lcdif. The reason to introduce lcdif_power_down is that we want lcdif to be in initial state when doing uboot reset or before kernel boot to make system stable, otherwise system may hang.

2015-11-12arm: discard relocation entries for secure textPeng Fan
The code such as PSCI in section named secure is bundled with u-boot image, and when bootm, the code will be copied to their runtime address same to compliation/linking address - CONFIG_ARMV7_SECURE_BASE. When compile the PSCI code and link it into the u-boot image, there will be relocation entries in .rel.dyn section for PSCI. Actually, we do not needs these relocation entries. If still keep the relocation entries in .rel.dyn section, r0 at line 103 and 106 in arch/arm/lib/relocate.S may be an invalid address which may not support read/write for one SoC. 102 /* relative fix: increase location by offset */ 103 add r0, r0, r4 104 ldr r1, [r0] 105 add r1, r1, r4 106 str r1, [r0] So discard them to avoid touching the relocation entry in arch/arm/lib/relocate.S.

2015-11-12nios2: add 10m50 devboard supportThomas Chou
Add 10m50 devboard support. It is based on the Golden Hardware Reference Design (GHRD), available at, http://rocketboards.org/foswiki/view/Documentation/ AlteraMAX1010M50RevCDevelopmentKitLinuxSetup Though we supported only one nios2-generic board in the past. Now, with the removal of the nios2-generic board dir, adding new nios2 boards to u-boot is easier than before. It should be helpful to add those boards supported in Linux mainline. There are only two such nios2 boards, the 3c120 devboard and 10m50 devboard. The nios2-generic is actually 3c120, and should restore the name. The 10m50 is this one.

2015-11-10ARM: tegra: add custom MMU setup on ARMv8Stephen Warren
This sets up a fine-grained page table, which is a requirement for noncached_init() to operate correctly. MMU setup code currently exists in a number of places: - A version in the core ARMv8 support code that sets up page tables that use very large block sizes that CONFIG_SYS_NONCACHED_MEMORY doesn't support. - Enhanced versions for fsl-lsch3 and zynmq that set up finer grained page tables. Ideally, rather than duplicating the MMU setup code yet again this patch would instead consolidate all the different routines into the core ARMv8 code so that it supported all use-cases. However, this will require significant effort since there appear to be a number of discrepancies[1] between different versions of the code, and between the defines/values by some copies of the MMU setup code use and the architectural MMU documentation. Some reverse engineering will be required to determine the intent of the current code. [1] For example, in the core ARMv8 MMU setup code, three defines named TCR_EL[123]_IPS_BITS exist, but only one of them sets the IPS field and the others set a different field (T1SZ) in the page tables. As far as I can tell so far, there should be no need to set different values per exception level nor to modify the T1SZ field at all, since TTBR1 shouldn't be enabled anyway. Another example is inconsistent values for *_VA_BITS between the current core ARMv8 MMU setup code and the various SoC- specific MMU setup code. Another example is that asm/armv8/mmu.h's value for SECTION_SHIFT doesn't match asm/system.h's MMU_SECTION_SHIFT; research is needed to determine which code relies on which of those values and why, and whether fixing the incorrect value will cause any regression.

2015-11-10armv8: allow custom MMU setup routines on ARMv8Stephen Warren
In order for noncached_init() to operate correctly, SoCs must set up a custom page table with fine-grained (2MiB) sections, which can be configured from noncached_init(). This is currently performed by arch/arm/cpu/armv8/{fsl-lsch3,zynqmp}/cpu.c by cut/pasting and re-implementing mmu_setup, enable_caches(), etc. There are some other reasons for the duplication there though, such as enabling icache early, and enabling dcaching earlier with a different configuration. This change makes mmu_setup() a weak implementation, so that the MMU setup code can be replaced without having to duplicate other code that calls it. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2015-11-10armv8: enable compilation with CONFIG_SYS_NONCACHED_MEMORYStephen Warren
The implementation of noncached_init() uses define MMU_SECTION_SIZE. Define this on ARM64. Move the prototype of noncached_{init,alloc}() to a location that doesn't depend on !defined(CONFIG_ARM64). Note that noncached_init() calls mmu_set_region_dcache_behaviour() which relies on something having set up translation tables with 2MB block size. The core ARMv8 MMU setup code does not do this by default, but currently relies on SoC specific MMU setup code. Be aware of this before enabling this feature on your platform!

2015-11-09mpc85xx/u-boot*.lds: remove _GLOBAL_OFFSET_TABLE_ definitionZhenhua Luo
In binutils-2.25, the _GLOBAL_OFFSET_TABLE_ symbols defined by PROVIDE in u-boot.lds overrides the linker built-in symbols (https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff; h=b893397a4b1316610f49819344817715e4305de9), so the linker is treating _GLOBAL_OFFSET_TABLE_ as a definition into the .reloc section. To align with the change of binutils-2.25, the _GLOBAL_OFFSET_TABLE_ symbol should not be defined in sections, and the symbols in linker generated .got section should be used(https://sourceware.org/ml/binutils/2008-09/ msg00122.html) Fixed the following build errors with binutils-2.25: | powerpc-poky-linux-gnuspe-ld.bfd: _GLOBAL_OFFSET_TABLE_ not defined in linker created .got Signed-off-by: Zhenhua Luo <zhenhua.luo@freescale.com> Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com>
2015-11-09Replace "extern inline" with "static inline"Måns Rullgård
A number of headers define functions as "extern inline" which is causing problems with gcc5. The reason is that starting with version 5.1, gcc defaults to the standard C99 semantics for the inline keyword. Under the traditional GNU inline semantics, an "extern inline" function would never create an external definition, the same as inline *without* extern in C99. In C99, and "extern inline" definition is simply an external definition with an inline hint. In short, the meanings of inline with and without extern are swapped between GNU and C99. The upshot is that all these definitions in header files create an external definition wherever those headers are included, resulting in multiple definition errors at link time. Changing all these functions to "static inline" fixes the problem since this works as desired in all gcc versions. Although the semantics are slightly different (a static inline definition may result in an actual function being emitted), it works as intended in practice. This patch also removes extern prototype declarations for the changed functions where they existed. Signed-off-by: Mans Rullgard <mans@mansr.com>
