* | | sunxi: Restore lowlevel_init usageHans de Goede2015-01-211-21/+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. This will allow us to add more flavours of binary-compatible ARCv1 CPUs like ARC600 if needed later on and all required ARCv2 CPUs (which are binary incompatible with ARCv1) in "arcv2" folder in subsequent commits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "reset.c" and "cpu.c" have no architecture-specific code at all. 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.

| * | arc: introduce separate section for interrupt vector tableIgor Guryanov2015-01-157-31/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even though existing implementation works fine in preparation to submission of ARCv2 architecture we need this change. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some cache operations ({i|d}cache_{enable|disable|status} or flush_dcache_all) are built and used even if CONFIG_SYS_{I|D}CACHE_OFF is set. This is required for force disable of caches on early boot. What if something was executed before U-boot and enabled caches (low-level bootloaders, previously run kernel etc.)? But if CPU doesn't really have caches any attempt to access cache-related AUX registers triggers instruction error exception. So for convenience we'll try to avoid exceptions by checking if CPU actually has caches (we check separately data and instruction cache existence) at all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current sunxi implementation uses gdata, which is going away. It also sets up DRAM before board_init_f() in SPL. There is really no reason to do much in s_init() since board_init_f() is called immediately afterwards. The only change is that we need our own implementation of board_init_f() which sets up DRAM before the BSS (which is in DRAM) is cleared. The s_init() code runs once for SPL and again for U-Boot proper. We shouldn't need to init the clock/timer/gpio/i2c init twice, so just have it in SPL. Signed-off-by: Simon Glass <sjg@chromium.org>

* | | TI ARMv7: Don't use GD before crt0.S has set itTom Rini2015-01-164-30/+11
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this change we set the gd pointer early so that we can store data in it. This becomes problematic for DM changes as well as being odd in general. Re-work the code paths so that we don't need to set the gd pointer so early and instead can rely upon the normal setting of it. In order to do this we do need to move certain calls from s_init into spl_board_init(), mainly preloader_console_init and save_omap_boot_params.

This commit adds support for gpio pins on the AXP209 pmic, the sunxi_gpio.c changes are universal, adding gpio support for the other AXP pmics (when necessary) should be a matter of adding the necessary axp_gpio_foo functions to their resp. drivers, and add "#define AXP_GPIO" to their header file. Note this commit only adds support for the non device-model version of the gpio code, patches for adding support to the device-model version are very welcome. The string representation for these gpio-s is AXP0-#, the 0 in the AXP0 prefix is there in case we need to support gpio-s on more then 1 pmic in the future.

* | sunxi: Fix buggy sun6i/sun8i DRAM size detection logicSiarhei Siamashka2015-01-143-18/+6

The current sun6i/sun8i DRAM size detection logic, which is inherited from the Allwinner code, relies on using a large magic signature with the hope that it is unique enough and unlikely to ever accidentally match this leftover garbage data in RAM. But this approach is inherently unsafe, as can be demonstrated using the following test program: /***** A testcase for reproducing the problem ******/ void main(int argc, char *argv[]) { size_t size, i; uint32_t *buf; /* Allocate the buffer */ if (argc < 2 || !(size = (size_t)atoi(argv[1]) * 1048576) || !(buf = malloc(size))) { printf("Need buffer size in MiB as a cmdline argument\n"); exit(1); } /* Fill it with the Allwinner DRAM "magic" values */ for (i = 0; i < size / 4; i++) buf[i] = 0xaa55aa55 + ((uintptr_t)&buf[i] / 4) % 64; /* Try to reboot */ system("reboot"); /* And wait */ for (;;) {} } /***************************************************/ If this test program is run on the device (giving it a large chunk of memory), then the DRAM size detection logic in u-boot gets confused after reboot and fails to initialize DRAM properly. A better approach is not to rely on luck and abstain from making any assumptions about the properties of the leftover garbage data in RAM. Instead just use a more reliable code for testing whether two different addresses refer to the same memory location.
