2017-01-29ARM: uniphier: use gd->bd->bi_dram for memory reserve on LD20 SoCMasahiro Yamada
For LD20 SoC, the last 64 byte of each DRAM bank is used for the dynamic training of DRAM PHY. The regions must be reserved in DT to prevent the kernel from using them. Now gd->bd->bi_dram reflects the actual memory banks. Just use it instead of getting access to the board parameters. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-01-29ARM: uniphier: detect RAM size by decoding HW register instead of DTMasahiro Yamada
U-Boot needs to set up available memory area(s) in dram_init() and dram_init_banksize(). It is platform-dependent how to detect the memory banks. Currently, UniPhier adopts the memory banks _alleged_ by DT. This is based on the assumption that users bind a correct DT in their build process. Come to think of it, the DRAM controller has already been set up before U-Boot is entered (because U-Boot runs on DRAM). So, the DRAM controller setup register seems a more reliable source of any information about DRAM stuff. The DRAM banks are initialized by preliminary firmware (SPL, ARM Trusted Firmware BL2, or whatever), so this means the source of the reliability is shifted from Device Tree to such early-stage firmware. However, if the DRAM controller is wrongly configured, the system will crash. If your system is running, the DRAM setup register is very likely to provide the correct DRAM mapping. Decode the SG_MEMCONF register to get the available DRAM banks. The dram_init() and dram_init_banksize() need similar decoding. It would be nice if dram_init_banksize() could reuse the outcome of dram_init(), but global variables are unavailable at this stage because the .bss section is available only after the relocation. As a result, SG_MEMCONF must be checked twice, but a new helper uniphier_memconf_decode() will help to avoid code duplication. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-01-29ARM: uniphier: shrink arrays of DDR-PHY parameters for LD20 SoCMasahiro Yamada
The two arrays ddrphy_{op,ip}_dq_shift_val, occupy more than 3.8 KB memory footprint, which is significant in SPL. There are PHY parameters for 5 boards, but they are actually not board specific, but SoC specific. After all, we just need to have 2 patterns, for LD20 and LD21. Also, the shift values are small enough to become "short" type instead of "int". This change will save about 3 KB memory footprint. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2017-01-28arm64: spin-table: add more information in Kconfig helpMasahiro Yamada
This feature seems to be sometimes misunderstood. The intention is: [1] Bring the slaves into the U-Boot proper image, not SPL (unless you have a special reason to do otherwise). [2] The operation must be done in a board (SoC) specific manner since how to wake the slaves from the Boot ROM is SoC specific. [3] The slaves must enter U-Boot proper after U-Boot relocates itself because the "cpu-release-addr" property points to the relocated memory area. [2] is already explained in the help. We can make [1] even clearer by mentioning "U-Boot proper" instead of "U-Boot". [3] is missing, so I am adding it to the list. Instead, "before the master CPU jumps to the kernel" is a matter of course, so removed. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Clock Driver This driver is ast2500-specific and is not compatible with earlier versions of this chip. The differences are not that big, but they are in somewhat random places, so making it compatible with ast2400 is not worth the effort at the moment. SDRAM MC driver The driver is very ast2500-specific and is completely incompatible with previous versions of the chip. The memory controller is very poorly documented by Aspeed in the datasheet, with any mention of the whole range of registers missing. The initialization procedure has been basically taken from Aspeed SDK, where it is implemented in assembly. Here it is rewritten in C, with very limited understanding of what exactly it is doing.

Add support for Watchdog Timer, which is compatible with AST2400 and AST2500 watchdogs. There is no uclass for Watchdog yet, so the driver does not follow the driver model. It also uses fixed clock, so no clock driver is needed. Add support for timer for Aspeed ast2400/ast2500 devices. The driver actually controls several devices, but because all devices share the same Control Register, it is somewhat difficult to completely decouple them. Since only one timer is needed at the moment, this should be OK. The timer uses fixed clock, so does not rely on a clock driver. Add sysreset driver, which uses watchdog timer to do resets and particular watchdog device to use is hardcoded (0) Reviewed-by: Simon Glass <sjg@chromium.org>

2017-01-24powerpc: Enable flush and invalidate dcache by range for MPC85xxTony O'Brien
Commit ac337168a unified functions to flush and invalidate dcache by range. These two functions were no-ops for SoCs other than 4xx and MPC86xx. Adding these functions seemed to be correct but introduced issues in some drivers when the dcache was flushed. While the root cause was under investigation, these functions were disabled in Commit cb1629f91a for affected SoCs, including the MPC85xx, to make the various drivers work. On the T208x USB stopped working after v2016.07 was pulled. After re-enabling the dcache functions for the MPC85xx it started working again. The USB and DPPA Ethernet drivers have been seen as operational after this change but other drivers cannot be tested.
