* | | sunxi: Move SPL s_init() code to board_init_f()Simon Glass2015-01-16-32/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | | arm: Add warnings about using gdataSimon Glass2015-01-16-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | We need to get rid of this SPL-specific setting of the global_data pointer. It is already set up in start.S immediately before board_init_f() is called, and there may be information there that is needed (e.g. pre-reloc malloc info).

* | | TI ARMv7: Don't use GD before crt0.S has set itTom Rini2015-01-16-30/+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.

* | sunxi: gpio: Add support for gpio pins on the AXP209 pmicHans de Goede2015-01-14-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some boards use GPIO-s on the pmic, one example of this is the A13-OLinuXino board, which uses gpio0 of the axp209 for the lcd-power signal. 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. At least A80 boards have 2 pmics, and we may end up needing to support gpio-s on both. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| | | | | | | | | | | | | | | | | | | | PLL1 on sun6i / sun8i also has a p factor which divides the clock by 2^p (to the power p). On sun6i the p factor is ignored, but on sun8i it is used and we were setting it to 1, resulting in the CPU running at 504 MHz instead of 1008 MHz, this commit fixes this.

* | sunxi: Fix buggy sun6i/sun8i DRAM size detection logicSiarhei Siamashka2015-01-14-18/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After reboot, reset or even short power off, DRAM typically retains the old stale data for some period of time (for this type of memory, the bits of data are stored in slowly discharging capacitors). 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.

* | sunxi: Fill memory before comparing it when doing dram init on sun6iHans de Goede2015-01-14-14/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sun8i boot0 code fills the DRAM with a "random" pattern before comparing it at different offsets to do columns, etc. detection. The sun6i boot0 code does not do it, instead relying on the memory contents being random enough to begin with for the memcmp to properly detect the wrap-around address, iow it is working purely by chance. Since our sun6i dram code was modelled after the boot0 code it contained the same issue. This commit fixes this by filling the memory with a unique, distinct pattern. The new mctl_mem_fill function this introduces is added as an inline helper in dram.h, so that it can be shared with the sun8i dram code. While at it move mctl_mem_matches to dram.h for re-use in sun8i too. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

* | sun6i: clock_set_pll5: Calculate k and m rather then hardcoding themHans de Goede2015-01-14-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Our old hardcoded k and m values are based on PLL5 being configured in steps of 48 MHz, which is correct for sun6i where the DRAM PLL runs at twice the DRAM CLK, which is usually configured in 24 MHz step. But on the A23 (sun8i) the PLL5 runs at half the DRAM CLK, so we require 12 MHz steps. This commit adjusts clock_set_pll5 to automatically select the best k and m depending on the requested clk rate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sunxi mmc controller has both an internal clock divider, as well as the divider in the mod0-clk for the mmc controller. The internal divider cannot be used, as it conflicts with the setting of clock sampling phases which is done in the mod0-clk, so it must be set to 0 (divide by 1). For some reason while the kernel has had this correct from day one, the u-boot sunxi mmc code has been using a fixed mod0-clk and setting its internal divider depending on the desired speed. This is something which we've inherited from the original Allwinner u-boot sources, but while this has been fixed in Allwinner's own u-boot code at least for the A23 and later upstream u-boot was still doing this wrong. This commit fixes this, thereby also fixing mmc support not working reliable on the A23 (which seems more sensitive to this) and possible also fixes some other sunxi mmc issues.

* arm: build arch memset/memcpy in Thumb2 modeStefan Agner2015-01-09-87/+142
| | | | | | | | | | | | | | | | | | | | | | Resynchronize memcpy/memset with kernel 3.17 and build them in Thumb2 mode (unified syntax). Those assembler files can be built and linked in ARM mode too, however when calling them from Thumb2 built code, the stack got corrupted and the copy did not succeed (the exact details have not been traced back). However, the Linux kernel builds those files in Thumb2 mode. Hence U-Boot should build them in Thumb2 mode too when CONFIG_SYS_THUMB_BUILD is set. To build the files without warning, some assembler instructions had to be replaced with their UAL compliant variant (thanks Jeroen for this input). To build the file in Thumb2 mode the implicit-it=always option need to be set to generate Thumb2 compliant IT instructions where needed. We add this option to the general AFLAGS when building for Thumb2. Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org> Signed-off-by: Stefan Agner <stefan@agner.ch>

* | mx25: Remove empty line after printing the reset causeFabio Estevam2015-01-08-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is an unneeded empty line after printing the reset cause: U-Boot 2015.01-rc4-00080-g0551a93 (Jan 06 2015 - 13:04:19) CPU: Freescale i.MX25 rev1.2 at 399 MHz Reset cause: POR Board: MX25PDK I2C: ready DRAM: 64 MiB MMC: FSL_SDHC: 0 Remove the extra "\n" when printing the reset cause.

* | ARM: UniPhier: add UART initialization routine for low-level debugMasahiro Yamada2015-01-08-0/+128
| | | | | | | | | | | | | | | | | | | | | | The low-level debugging functions are useful to debug the early boot stage where the full UART driver is not available. UniPhier SoCs need to initialize the UART port 0 to use this feature. The initialization routine is called at the very entry of the lowlevel_init().

* | ARM: UniPhier: enable output of system busMasahiro Yamada2015-01-08-0/+15
| | | | | | | | | | | | | | | | For NAND boot on PH1-LD4, PH1-sLD8, and some other SoCs, the output of the system bus is disabled by default. It must be enabled by software to have access to the system bus. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* | ARM: UniPhier: fix SRAM size on support cardMasahiro Yamada2015-01-08-3/+3
| | | | | | | | | | | | | | | | | | | | The max size of available memories on slot0 and slot1 is 32MB because - EA[25] signal is not output on the save-pin mode which is used PH1-LD4 or later SoCs. - EA[25] signal is not connected by the limitation (or bug?) of the PLD logic of DCC support card.
