2017-02-22ARM: uniphier: deassert RST_n of eMMC device for LD11/LD20Masahiro Yamada
For LD11 and LD20 SoCs, the RST_n pin is asserted by default. If the EXT_CSD[162], bit[1:0] (RST_n_ENABLE) is fused, the eMMC device would stay in the reset state until its RST_n pin is deasserted by software. Currently, this is cared by an ad-hoc way because the eMMC hardware reset provider is not supported in U-Boot for now. This code should be re-written once the "mmc-pwrseq-emmc" binding is supported.

2017-02-22ARM: uniphier: add DRAM PHY clock duty adjustment for LD20 SoCKotaro Hayashi
If the DRAM clock duty does not meet the allowable tolerance, it is marked in an efuse register. If the register is fused, the boot code should compensate for the DRAM clock duty error.

2017-02-22ARM: uniphier: rework spl_boot_device() and related codeMasahiro Yamada

2017-02-22ARM: uniphier: move spl_boot_mode() to a separate fileMasahiro Yamada
The spl_boot_mode() is unrelated to the other code in this file. Besides, this function is only called from common/spl/spl_mmc.c, so it is reasonable to guard with CONFIG_SPL_MMC_SUPPORT. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-02-22ARM: uniphier: move MMC code to a separate fileMasahiro Yamada
Currently, arch/arm/mach-uniphier/boot-mode/boot-mode.c is messed up with unrelated code; there is no reason why the "mmcsetn" command must be placed in this file. Split out the MMC code into arch/arm/mach-uniphier/mmc-first-dev.c. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Support the following DT properties: "bias-disable" "bias-pull-up" "bias-pull-down" "bias-pull-pin-default" "input-enable" "input-disable" My main motivation is to support pull up/down biasing. For Pro5 and later SoCs, the pupdctrl register number is the same as the pinmux number, so this feature can be supported without having big pin tables.

Since commit 26b09c022ab6 ("ARM: uniphier: move SBC and Support Card init code to U-Boot proper"), the System Bus is initialized by board_init(). The show_board_info() is called from board_init_f() by default, so the revision register of the Micro Support Card may not be accessed at this point.

2017-02-22video: mxsfb: Fix reset hang when videomode variable is not presentFabio Estevam
Currently the system hangs when the 'videomode' variable is not present and a reset command is issued: => setenv videomode => saveenv => reset (Board hangs) lcdif_power_down() assumes that the LCDIF controller has been properly configured and enabled, which may not be true. To fix this issue check whether panel.frameAdrs has been initialized and in case it has not been initialized, do not continue with the LCDIF powerdown sequence. Tested on a imx7dsabresd board.

2017-02-21x86: Force 32-bit jumps in interrupt handlersJ. Tang
Depending upon the compiler used, IRQ entries could vary in sizes. With GCC 5.x, the code generator will use short jumps for some IRQ entries but near jumps for others. For example, GCC 5.4.0 generates the following: $ objdump -d interrupt.o <snip> 00000207 <irq_18>: 207: 6a 12 push $0x12 209: eb 85 jmp 190 <irq_common_entry> 0000020b <irq_19>: 20b: 6a 13 push $0x13 20d: eb 81 jmp 190 <irq_common_entry> 0000020f <irq_20>: 20f: 6a 14 push $0x14 211: e9 7a ff ff ff jmp 190 <irq_common_entry> 00000216 <irq_21>: 216: 6a 15 push $0x15 218: e9 73 ff ff ff jmp 190 <irq_common_entry> This causes a problem in cpu_init_interrupts(), because the IDT setup assumed same sizes for all IRQ entries. GCC 4.x always generated 32-bit jumps, so this previously was not a problem. The fix is to force 32-bit near jumps for all entries within the inline assembly. This works for GCC 5.x, and 4.x was already using that form of jumping. Signed-off-by: Jason Tang <tang@jtang.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2017-02-12flash: complete CONFIG_SYS_NO_FLASH move with renamingMasahiro Yamada
We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is not completed. Finish this work by the tool. During this move, let's rename it to CONFIG_MTD_NOR_FLASH. Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH" than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will make the code more readable. Besides, negative meaning symbols do not fit in obj-$(CONFIG_...) style Makefiles. This commit was created as follows: [1] Edit "default n" to "default y" in the config entry in common/Kconfig. [2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH" [3] Rename the instances in defconfigs by the following: find . -path './configs/*_defconfig' | xargs sed -i \ -e '/CONFIG_SYS_NO_FLASH=y/d' \ -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/' [4] Change the conditionals by the following: find . -name '*.[ch]' | xargs sed -i \ -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \ -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \ -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \ -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/' [5] Modify the following manually - Rename the rest of instances - Remove the description from README - Create the new Kconfig entry in drivers/mtd/Kconfig - Remove the old Kconfig entry from common/Kconfig - Remove the garbage comments from include/configs/*.h Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
