kconfig: add board Kconfig and defconfig files This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

MIPS: Simplify CONFIG_SYS_CPU values Rather than having the values for CONFIG_SYS_CPU depend upon each architecture revision, have them depend upon the more general CONFIG_CPU_MIPS32 & CONFIG_CPU_MIPS64 which in turn depend upon the architecture revisions. This is done in preparation for adding MIPSr6 support, which would otherwise need to introduce new cases here. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

MIPS: allow systems to skip loads during cache init Current MIPS systems do not require that loads be performed to force the parity of cache lines, a simple invalidate by clearing the tag for each line will suffice. Thus this patch makes the loads & subsequent second invalidation conditional upon the CONFIG_SYS_MIPS_CACHE_INIT_RAM_LOAD option, and defines that for existing mips32 targets. Exceptions are malta where this is known to be unnecessary, and qemu-mips where caches are not implemented.

mips: mt76xx: Implement new d-cache fix in last_stage_init() With commit 06985289d452 ("watchdog: Implement generic watchdog_reset() version") the init sequence has changed in arch_misc_init(), resulting in a re-appearance of the d-cache issue on MT7688 boards (e.g. gardena). When this happens, the first (or sometimes later ones as well) TFTP command hangs and does not complete correctly. This leads to the assumption that the d-cache is not in a clean state once the ethernet driver is called (d-cache is used here for the buffers). The old work- around with the cache flush somehow does not work any more now with the new code change. Unfortunately adding CONFIG_SYS_MALLOC_CLEAR_ON_INIT also did not fix this issue. With v2019.07-rc3 it shows again. The time of accessing the data seems to be very important here. It needs to be "very late" in the boot process. Testing has shown, that copying a 64KiB area in DDR at a very late bootup time, directly before calling into the prompt, fixes this issue. Flushing of the complete d-cache does not seem to necessary, as this copy alone seems to fix this problem.

mips: mtmips: add SPL support This patch adds SPL support for mtmips platform. The lowlevel architecture is split into SPL and the rest parts are built into a memory loadable u-boot image. Optional SPL_DM and OF_CONTROL are also supported. The increment of size is very small (< 10 KiB) if SPL_DM and OF_CONTROL are not enabled and the memory bootable u-boot (u-boot.img) is generated automatically so there is not need to add a separate config for it. A lzma compressed payload (u-boot-lzma.img) is also generated and it will be combined with u-boot-spl.bin to form the unified ROM bootable binary u-boot-mtmips.bin. A spl loader is added to support uncompress the payload. Reviewed-by: Stefan Roese <sr@denx.de> Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>

For instance this is the case when U-Boot is used as ROM in Qemu or booted from parallel NOR flash. When U-Boot is booted from RAM (e.g. loaded there by SPL), the exception vectors need to be setup dynamically, which is done in follow-up commits.

Enable this to include exception vectors in the U-Boot image. This is
required if the U-Boot entry point is equal to the address of the
CPU reset exception vector (e.g. U-Boot as ROM loader in Qemu,
U-Boot booted from parallel NOR flash).
Disable this, if the U-Boot image is booted from DRAM (e.g. by SPL).
In that case the image size will be reduced by 0x500 bytes.

This is the base address for a memory block, which is used for

Normally this is CKSEG0. If the MIPS system needs to move this block

MIPS: make size of relocation table fixed but configurable Currently the size of the relocation table will be shrunk to the actual size needed. Although this gives a maximal space saving, it messes up the _end symbol. This breaks features like appended DTBs because the _end symbol doesn't point to the real end of the U-Boot binary. Remove the size shrinking and make the size of the relocation table fixed but configurable. This follows the Linux approach and the user can adjust the size to his needs. Also rename the relocation table section from .rel to .data.reloc to follow the Linux approach and to avoid ambiguities with the .rel.* sections added by the linker.

MIPS: Split I & D cache line size config Allow L1 Icache & L1 Dcache line size to be specified separately, since there's no architectural mandate that they be the same. The [id]cache_line_size functions are tidied up to take advantage of the fact that the Kconfig entries are always present to simply check them for zero rather than needing to #ifdef on their presence.

Select this (or let it be auto-selected by not defining any cache
sizes) in order to allow U-Boot to automatically detect the sizes
of caches at runtime. This has a small cost in code size & runtime
so if you know the cache configuration for your system at compile
time it would be beneficial to configure it.
MIPS: kconfig: add option for MIPS_L1_CACHE_SHIFT Add Kconfig symbol for L1 cache shift like the kernel does. The value of CONFIG_SYS_CACHELINE_SIZE is not a reliable source for ARCH_DMA_MINALIGN anymore, because it is optional on MIPS. If CONFIG_SYS_CACHELINE_SIZE is not defined by a board, the cache sizes are automatically detected and ARCH_DMA_MINALIGN would be set to 128 Bytes. The default value for CONFIG_MIPS_L1_CACHE_SHIFT is 5 which corresponds to 32 Bytes. All current MIPS boards already used that value. While on it, fix the Malta board to use a value of 6 like the kernel port does. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

MIPS: L2 cache support This patch adds support for initialising & maintaining L2 caches on MIPS systems. The L2 cache configuration may be advertised through either coprocessor 0 or the MIPS Coherence Manager depending upon the system, and support for both is included. If the L2 can be bypassed then we bypass it early in boot & initialise the L1 caches first, such that we can start making use of the L1 instruction cache as early as possible. Otherwise we initialise the L2 first such that the L1s have no opportunity to generate access to the uninitialised L2. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

MIPS: Support dynamic I/O port base address The existing mips_io_port_base variable isn't suitable for use early during boot since it will be stored in the .data section which may not be writable pre-relocation. Fix this by moving the I/O port base address into struct arch_global_data. In order to avoid adding this field for all targets, make this dependant upon a new Kconfig entry CONFIG_DYNAMIC_IO_PORT_BASE. Malta is the only board which sets a non-zero I/O port base, so select this option only for Malta. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

MIPS: start.S: make boot config at offset 0x10 configurable Some MIPS systems store some board-specific boot configuration in the U-Boot binary at offset 0x10. This is used by Malta boards and by Lantiq/Intel SoC's when booting from parallel NOR flash. Convert the hard-coded values to Kconfig options to remove such board-specific stuff out of the generic start.S code. This also deprecates the config option CONFIG_SYS_XWAY_EBU_BOOTCFG.

kconfig: add board Kconfig and defconfig files This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.
