* ARM: uniphier: add simple eMMC load APIs instead of ROM APIMasahiro Yamada2017-02-23-58/+195
| | | | | | | | | | | Re-use of routines embedded in the Boot ROM requires a function pointer table for each SoC. This is not nice in terms of the maintainability in a long run. Implement simple eMMC load APIs that are commonly used for LD11, LD20, and hopefully future SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: deassert RST_n of eMMC device for LD11/LD20Masahiro Yamada2017-02-23-1/+25
| | | | | | | | | | | | | 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.

* ARM: uniphier: add DRAM PHY clock duty adjustment for LD20 SoCKotaro Hayashi2017-02-23-2/+8
| | | | | | | | | | 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.

* ARM: uniphier: remove dram_nr_ch from board parametersMasahiro Yamada2017-02-23-26/+18

* ARM: uniphier: rework spl_boot_device() and related codeMasahiro Yamada2017-02-23-344/+312
| | | | | | | | The current implementation has ugly switch statements here and there, and duplicates similar code. Rework it using table lookups for SoC data and reduce code duplication. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: move spl_boot_mode() to a separate fileMasahiro Yamada2017-02-23-24/+35
| | | | | | | | 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>
* ARM: uniphier: move MMC code to a separate fileMasahiro Yamada2017-02-23-38/+47
| | | | | | | | | | 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.

* ARM: uniphier: print Support Card info very lateMasahiro Yamada2017-02-23-7/+4
| | | | | | | | | | | 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. Show its revision after the System Bus is initialized. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

| | | | | | | | | | | | | | | | | | Intel Mobile Internet Device (MID) platforms have special treatment in some cases, such as CPU enumeration or boot parameters configuration.

* x86: Force 32-bit jumps in interrupt handlersJ. Tang2017-02-21-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
