| * ARM: UniPhier: remove __packed that causes a problem on GCC 4.9Masahiro Yamada2015-01-23-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DDR PHY training function, ddrphy_prepare_training() would not work if compiled with GCC 4.9. The struct ddrphy (arch/arm/include/asm/arch-uniphier/ddrphy-regs.h) is specified with __packed because it represents a hardware register mapping, but it turned out to cause a problem on GCC 4.9. If -mno-unaligned-access is specified (yes, it is in arch/arm/cpu/armv7/config.mk), GCC 4.9 is aware of the __attribute__((packed)) and generates extra instructions to perform the memory access in a way that does not cause unaligned access. (Actually it is not need here because the register base, the first argument of the ddrphy_prepare_training(), is always given with a 4-byte aligned address.) Anyway, as a result, readl() / writel() is divided into byte-wise accesses. The problem is that this hardware only accepts 4-byte register access. Byte-wise accesses lead to unexpected behavior. There are some options to avoid this problem. [1] Remove -mno-unaligned-access [2] Add __aligned(4) along with __packed to struct ddrphy [3] Remove __packed from struct ddrphy [1] solves the problem for ARMv7, but it does not for pre-ARMv6 and ARMv6-M architectures where -mno-unaligned-access is default. So, [1] does not seem reasonable in terms of code portability. Both [2] and [3] work well, but [2] seems too much. All the members of struct ddrphy have the u32 type. No padding would be inserted even if __packed is dropped. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Reviewed-by: Tom Rini <trini@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement MIPS specific setup of the gd_t structure to support pre-relocation malloc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The common code just needs the C0_COUNT as free running counter, without the need of writing and checking C0_COMPARE. The function get_tbclk() is still implemented here instead of changing all places of CONFIG_SYS_MIPS_TIMER_FREQ to CONFIG_SYS_TIMER_RATE. The change was tested on a MIPS32 system, but as the MIPS64 code was/is the same, this should be no problem. Signed-off-by: Thomas Langer <thomas.langer@lantiq.com>

* | | sunxi: Restore lowlevel_init usageHans de Goede2015-01-21-22/+21
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2 recent sunxi changes have removed the usage of lowlevel_init by moving some code around and then setting CONFIG_SKIP_LOWLEVEL_INIT. This is problematic for 2 reasons: 1) It does not just stop s_init from being called, it also stops cpu_init_cp15 from getting called, which is undesirable. 2) We want u-boot.bin to be usable standalone, without SPL, some people e.g. use an upstream u-boot.bin together with Allwinner's boot0 loader. So u-boot.bin must (re)initialize the gpios, timer, etc. This commit restores the lowlevel_init / s_init usage, while keeping the changes to no longer use the global-data (gd) struct in the SPL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As a preparation to ARCv2 port submission we rename "arc700" folder to "arcv1" which stands for ARCv1 ISA also known as ARCompact.

Others are applicable to either ARC CPU. This change is a preparation to submission of ARCv2 architecture port. Even though ARCv1 and ARCv2 ISAs are not binary compatible most of built-in modules still have the same programming model - AUX registers are mapped in the same addresses and hold the same data (new featues extend existing ones). So only low-level assembly code (start-up, interrupt handlers) is left as CPU(actually ISA)-specific. This significantyl simplifies maintenance of multiple CPUs/ISAs.

In case of ARCv2 interrupt vector table consists of just addresses of corresponding handlers. And if those addresses will be in .text section then assembler will encode them as everything in .text section as middle-endian and then on real execution CPU will read swapped addresses and will jump into the wild. Once introduced new section is situated so .text section remains the first which allows us to use common linker option for linking everything to a specified CONFIG_SYS_TEXT_BASE.
