* ARM: UniPhier: remove unnecessary ifdef conditionalMasahiro Yamada2015-03-24-2/+0
| | | | | | | | The callee (arch/arm/lib/cache-cp15.c) has a #ifdef CONFIG_SYS_DCACHE_OFF conditional. The same conditional in the caller (arch/arm/mach-uniphier/cache_uniphier.c) is redundant. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: disable L2 cache by lowlevel_init of U-Boot properMasahiro Yamada2015-03-24-17/+5
| | | | | | | | | | | | The L2 cache is used as a temporary SRAM on SPL. Now the secondary CPUs store the necessary code for jumping to Linux on their L1 I-caches. So, the L2 cache can be disabled much earlier, at the very entry of U-Boot proper (lowlevel_init). This makes the boot sequence clearer. Also, as the L1 cache has been disabled by the start.S, enable_caches() does not need to do it again. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: optimize kicking secondary CPUs codeMasahiro Yamada2015-03-24-72/+38
| | | | | | | | | | | | | | 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.

| | | | | | | To remove the ifdef conditional of CONFIG_SKIP_LOWLEVEL_INIT, add late_lowlevel_init.S to U-Boot proper. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: move init stack area just below TEXT_BASEMasahiro Yamada2015-03-24-1/+1

* ARM: UniPhier: add CONFIG_SPL_MAX_FOOTPRINTMasahiro Yamada2015-03-24-0/+2
| | | | | | | The Boot ROM of UniPhier platform only loads 64KB image. We should always make sure that SPL memory footprint is less than that. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: use CONFIG_SPL_STACK to define SPL stack pointerMasahiro Yamada2015-03-24-8/+14
| | | | | | | 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: enable Driver Model and UART on SPLMasahiro Yamada2015-03-24-6/+14
| | | | | | | | | | | Enable CONFIG_SPL_DM and CONFIG_SPL_SERIAL_SUPPORT, which provide Driver Model UART support on SPL. CONFIG_SYS_SPL_MALLOC_{START,SIZE} should be dropped because simple malloc is preferred on SPL. Dlmalloc requires some static variables on .data section that is not available yet for NOR boot mode etc. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: enable CONFIG_PANIC_HANGMasahiro Yamada2015-03-24-1/+4

* ARM: UniPhier: move UART pin settings to SPLMasahiro Yamada2015-03-24-49/+96

* ARM: UniPhier: move platform devices to SPLMasahiro Yamada2015-03-24-2/+2
| | | | | | | | | | Since we do not have OF_CONTROL support for SPL, platform devices are necessary to enable Driver Model on SPL. To prepare for that, move platdevice.o to SPL and enable it by CONFIG_SPL_DM. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* ARM: UniPhier: include PH1-LD4 Makefile from PH1-sLD8Masahiro Yamada2015-03-24-16/+1

* ARM: UniPhier: remove unnecessary CONFIG_SYS_SOCMasahiro Yamada2015-03-24-3/+0
