* sunxi: Hummingbird_A31_defconfig: Enable VGA output through external DACChen-Yu Tsai2015-01-14-0/+2
| | | | | | | | | | The Hummingbird A31 uses an external DAC connected to the LCD0 outputs for the on board VGA output. The DAC has a power control that's toggled by GPIO.

| | | | | | | | | | | Using an external DAC for VGA output was available on sun5i. Since some other SoCs don't have a builtin TV encoder, but might have use for a VGA output, enable the option for the platforms that don't have TV encoders.

* console: Use pre-console buffer to get complete log on all consolesSiarhei Siamashka2015-01-14-5/+41
| | | | | | | | | | | | | | | | | | | Currently the pre-console buffer can accumulate early log messages and flush them to the serial console as soon as it becomes available. This patch just adds one more pre-console buffer flushing point and does all the same for the other consoles too. This is particularly useful for the vga/hdmi/lcd console, where we can see all the older messages now (except for the log messages from SPL). Naturally, we don't want to get an extra copy of the log messages on the serial console again at the second flushing point, so the serial console has to be explicitly filtered out.

* sun7i: Add support for taking CPUs offline via PSCIJan Kiszka2015-01-14-0/+171
| | | | | | | | | | | Based on the original version by Marc Zyngier. It adds a psci_cpu_off implementation for the A20 SoC. The mechanism works by first preparing the calling CPU to go offline (disable and flush cache, disable SMP), then requesting CPU 0 to pull the plug. The request is sent as FIQ on SGI15.

* sunxi: video: Add a hpd_delay parameter to configure hpd delayHans de Goede2015-01-14-5/+12
| | | | | | | | | | | | | In some extreme cases it may be necessary to wait 1.5 seconds or more for a hpd signal to show up (and be able to read edid info), but we do not want to penalize all headless boots with an extra second boot delay, so add a hpd_delay parameter which can be set through the video-mode env. variable.

| | | | | | | | | | Before video output support can be enabled on the A13-OLinuXinoM, bootm_size must first be reduced to take into account that the framebuffer is shaved of the top of the DRAM.

* sunxi: gpio: Add support for gpio pins on the AXP209 pmicHans de Goede2015-01-14-0/+112
| | | | | | | | | | | | | | | | | | | | | | 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>

* 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: Fix CONFIG_UART0_PORT_F build and add it to menuconfigSiarhei Siamashka2015-01-14-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | The CONFIG_UART0_PORT_F option has been supported since http://git.denx.de/?p=u-boot.git;a=commit;h=ff2b47f6a9cc1025 This option is primarily useful only for low level u-boot debugging on tablets, where normal UART0 is difficult to access and requires device disassembly and/or soldering. This patch now allows it to be selected from menuconfig. A dependency on SPL_FEL is added because u-boot does not support booting from NAND yet and also booting from SD card is impossible when a MicroSD breakout board is plugged into the SD slot. Additionally a compilation problem is fixed: common/spl/built-in.o: In function `spl_mmc_load_image': /tmp/u-boot-sunxi/common/spl/spl_mmc.c:94: undefined reference to `mmc_initialize' /tmp/u-boot-sunxi/common/spl/spl_mmc.c:96: undefined reference to `find_mmc_device' /tmp/u-boot-sunxi/common/spl/spl_mmc.c:104: undefined reference to `mmc_init' scripts/Makefile.spl:206: recipe for target 'spl/u-boot-spl' failed Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
