Need to call lcdif_power_down to make lcdif in initial state before kernel boot. Similar issue for uboot reset with lcdif enabled, system will hang after serveral times resetting. Need to let lcdif initial state to make all go well.

We need to power down lcdif before uboot reset to make reset can pass stress test. Signed-off-by: -
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. Signed-off-by:

Support lcdif display: 1. Add pinmux and pad settings for LCDIF 2. Introduce setup_lcd to do the settings for LCDIF 3. Enable VIDEO related macros in board header files 4. Add a new env videomode which is needed by mxsfb.c. The settings for videomode in this patch is for TFT43AB. 5. Tested on mx6ul 14x14/9x9 evk. Signed-off-by: -

1. Move WDOG3_BASE_ADDR to '#if !(defined(__ASSEMBLY__))'. 2. Add i.MX6UL LCDIF register base address. And Introduce LCDIF1_BASE_ADDR to support runtime check. 3. include <asm/imx-common/regs-lcdif.h> for imx-regs.h to avoid building error for mxsfb.c, since mxsfb.c use imx-regs.h. Signed-off-by: -
Share one lcdif structure for i.MXes. 1. Discard struct mxs_lcdif_regs from imx-regs.h of i.MX7 2. Add i.MX6SX/6UL/7D support in imx-lcdif.h of imx-common Signed-off-by: -

1. add basic psci support for imx7 chip. 2. support cpu_on and cpu_off. 3. switch to non-secure mode when boot linux kernel. 4. set csu allow accessing all peripherial register in non-secure mode. Signed-off-by:
-
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.

Rename board nios2-generic to 3c120_devboard. Since nios2 is converted to driver model and device tree control of u-boot, the nios2-generic board directory is removed. We can rename the board back to a real board name. Now the boards maintained in u-boot mainline are the same as Linux kernel, namely 3c120 and 10m50. Signed-off-by:

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. Signed-off-by:
