2018-11-02MIPS: make size of relocation table fixed but configurableDaniel Schwierzeck
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.

2018-09-23mips: Add Gardena Smart-Gateway board supportStefan Roese
The Gardena Smart-Gateway boards have a MT7688 SoC with 128 MiB of RAM and 8 MiB of flash (SPI NOR) and additional 128MiB SPI NAND storage. This patch also includes 2 targets. One is the target that can be programmed into the SPI NOR flash and a 2nd target "xxx-ram" is added to support loading and booting via an already running U-Boot version. This allows easy development and testing without the need to flash the image each time.

This patch adds basic support for the MediaTek MT7620/88 SoCs. Parts of the code is copied from the MediaTek GitHub repository: https://github.com/MediaTek-Labs/linkit-smart-uboot.git The mt7628a.dtsi file is imported from Linux v4.17. Support for the LinkIt Smart 7688 module and the Gardena Smart Gateway both based on the MT7688 will be added in further patches.

2018-09-22MIPS: cache: remove config option CONFIG_SYS_MIPS_CACHE_MODEDaniel Schwierzeck
Caches should be configured to mode CONF_CM_CACHABLE_NONCOHERENT (or CONF_CM_CACHABLE_COW when a CM is available). There is no need to make this configurable. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2018-09-22MIPS: cache: make index base address configurableDaniel Schwierzeck
The index base address used for the cache initialisation is currently hard-coded to CKSEG0. Make this value configurable if a MIPS system needs to have a different address (e.g. in SRAM or ScratchPad RAM). Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2018-09-22MIPS: cache: optimise changing of k0 CCA modeDaniel Schwierzeck
Changing the Cache Coherency Algorithm (CCA) for kernel mode requires executing from KSEG1. Thus do a jump from KSEG0 to KSEG1 before changing the CCA mode. Jump back to KSEG0 afterwards. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2018-09-22MIPS: cache: reimplement dcache_[status, enable, disable]Daniel Schwierzeck
Those functions are not needed during cache init and can be implemented in C. Only support the safe disabling of caches when this is required for booting an OS. Reenabling caches is much harder to implement if an optional coherency manager must be supported. As there is no real use-case anyway, dcache_enable is implemented with an error message.

2018-09-22MIPS: start.S: make boot config at offset 0x10 configurableDaniel Schwierzeck
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.

The only platform left for the AU1x00 SoCs was the pb1x00 platform, an apparent clone of the dbau1x00 platform. As pb1x00 had no listed maintainer I am assuming that it is also orphaned.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-02-18fdt: Implement weak arch_fixup_fdt()Alexey Brodkin
Only ARM and in some configs MIPS really implement arch_fixup_fdt(). Others just use the same boilerplate which is not good by itself, but what's worse if we try to build with disabled CONFIG_CMD_BOOTM and enabled CONFIG_OF_LIBFDT we'll hit an unknown symbol which was apparently implemented in arch/xxx/lib/bootm.c. Now with weak arch_fixup_fdt() right in image-fdt.c where it is used we get both items highlighted above fixed.
