* ARM: uniphier: unify low-level debug init codeMasahiro Yamada2015-09-25-1/+1
| | | | | | | Move init code of low-level debug into a single file. This is helpful to create an image that runs on multiple SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: uniphier: refactor LED functionMasahiro Yamada2015-09-25-1/+0
| | | | | | | | | | The macro, led_write(), is now only used in C sources. There is no more reason to keep the tricky assembly macro. Replace it with a new C function led_puts(). Also, rename board.h to micro-support-card.h. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: remove unnecessary cache coherency codeMasahiro Yamada2015-05-31-23/+1
| | | | | | | | Cache coherency for SMP is cared by Linux. In U-Boot, the secondary CPU(s) are just sleeping. Nothing in memory is shared with the primary CPU. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: optimize kicking secondary CPUs codeMasahiro Yamada2015-03-24-6/+36
| | | | | | | | | | | | | | Currently, the secondary CPU(s) are kicked three times: Boot ROM ---(kick)--> SPL ---(kick)--> U-boot ---(kick)--> Linux. It makes the boot sequence very complicated. This commit merges the first and the second kicks, so the secondary CPU(s) can directly jump from SPL to Linux. arch/arm/mach-uniphier/smp.S is no longer necessary. Linux boot test passed.

* ARM: UniPhier: fix typos in commentsMasahiro Yamada2015-03-24-7/+7

* ARM: UniPhier: use CONFIG_SPL_STACK to define SPL stack pointerMasahiro Yamada2015-03-24-3/+4
| | | | | | | Ifdef conditionals for CONFIG options are not Kconfig-friendly. Instead, define CONFIG_SPL_STACK to prepare for Kconfig moves. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: remove SSC_WAY_SIZE and SSC_NUM_ENTRIES macrosMasahiro Yamada2015-03-01-3/+7
| | | | | | | | | | | | | Each way of the system cache has 256 entries for PH1-Pro4 and older SoCs, whereas 512 entries for PH1-Pro5 and newer SoCs. The line size is still 128 byte. Thus, the way size is 32KB/64KB for old/new SoCs. To keep lowlevel_init SoC-independent, set BOOT_RAM_SIZE to the constant value 32KB. It is large enough for temporary RAM and should work for all the SoCs of UniPhier family. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: include <mach/*.h> instead of <asm/arch/*.h>Masahiro Yamada2015-03-01-4/+4
| | | | | | | | | Since commit 0e7368c6c426 (kbuild: prepare for moving headers into mach-*/include/mach), we can replace #include <asm/arch/*.h> with <mach/*.h> so we do not need to create the symbolic link during the build. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: move SoC sources to mach-uniphierMasahiro Yamada2015-03-01-0/+163
Move arch/arm/cpu/armv7/uniphier/* -> arch/arm/mach-uniphier/* Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
