2017-03-14armv8: fsl-lsch2: add workaround for erratum A-010635Tang Yuantian
Read DMA operations causes CRC error on armv8 chassis 2 platforms due to the erratum A-010635. In order to support sata on these platforms, ECC needs to be disabled. Signed-off-by: Tang Yuantian <yuantian.tang@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
2017-03-14armv8: layerscape: Update early MMU for DDR after initializationYork Sun
In early MMU table, DDR has to be mapped as device memory to avoid speculative access. After DDR is initialized, it needs to be updated to normal memory to allow code execution. To simplify the code, dram_init() is moved into a common file as a weak function. Signed-off-by: York Sun <york.sun@nxp.com>
2017-03-14armv8: mmu: Add a function to change mapping attributesYork Sun
Function mmu_change_region_attr() is added to change existing mapping with updated PXN, UXN and memory type. This is a break-before-make process during which the mapping becomes fault (invalid) before final attributres are set. Signed-off-by: York Sun <york.sun@nxp.com>
2017-03-14armv8: ls2080a: Drop early MMU for SPL buildYork Sun
Early MMU improves performance especially on emulators. However, the early MMU is left enabled after the first stage of SPL boot. Instead of flushing D-cache and dealing with re-enabling MMU for the second stage U-Boot, disabling it for SPL build simplifies the process. The performance penalty is unnoticeable on the real hardware. As of now, SPL boot is not supported by existing emulators. So this should have no impact on emulators.

2017-03-14armv8: layerscape: Fix the sequence of changing MMU tableYork Sun
This patch follows the break-before-make process when making changes to MMU table. MMU is disabled before changing TTBR to avoid any potential race condition. Signed-off-by: York Sun <york.sun@nxp.com>

2017-03-14armv8: layerscape: Rewrite memory reservationYork Sun
For ARMv8 Layerscape SoCs, secure memory and MC memorey are reserved at the end of DDR. DDR is spit into two or three banks. This patch reverts commit aabd7ddb and simplifies the calculation of reserved memory, and moves the code into common SoC file. Secure memory is carved out first. DDR bank size is reduced. Reserved memory is then allocated on the top of available memory. U-Boot still has access to reserved memory as data transferring is needed. Device tree is fixed with reduced memory size to hide the reserved memory from OS. The same region is reserved for efi_loader. Signed-off-by: York Sun <york.sun@nxp.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>

The LS1043A rev1.1 silicon supports two types of GIC offset: 4K alignment and 64K alignment. The bit SCFG_GIC400_ALIGN[GIC_ADDR_BIT] is used to choose which offset will be used. The LS1043A rev1.0 silicon only supports the CIG offset with 4K alignment. If GIC_ADDR_BIT bit is set, 4K alignment is used, or else 64K alignment is used. 64K alignment is the default setting. Overriding the weak smp_kick_all_cpus, the new impletment is able to detect GIC offset. The default GIC offset in kernel device tree is using 4K alignment, it need to be fixed if 64K alignment is detected.

2017-01-18armv8/fsl-lsch2: refactor the clock system initializationHou Zhiqiang
Up to now, there are 3 kind of SoCs under Layerscape Chassis 2, like LS1043A, LS1046A and LS1012A. But the clocks tree has a lot of differences, for instance, the IP modules have different dividers to derive its clock from Platform PLL. And the core cluster PLL and platform PLL maybe have different reference clocks, such as LS1012A. Another problem is which clock/PLL should be described by sys_info->freq_systembus, it is confused in Layerscape Chissis 2. This patch is to bind the sys_info->freq_systembus to the Platform PLL, and handle the different divider of IP modules separately between different SoCs, and separate reference clocks of core cluster PLL and platform PLL.

If not enabled, the cache is not coherent with other cores and data corruption could occur.

For prepending some board specific header area to U-Boot images we were so far including a header file with a macro definition containing the actual header specification. This works fine if there are just a few statements and if there is only one alternative. However adding more complex code quickly gets messy with this approach, so let's just drop that intermediate macro and let the #include actually insert the code directly. This converts the callers and the callees, but doesn't change anything at this point.
