MIPS: make size of relocation table fixed but configurable

2018-11-02T21:39:07+00:00

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: mt7628a.dtsi: Add SPI clock-frequency property

2018-09-23T12:27:51+00:00

This patch adds the clock-frequency property to the SPI controller
DT node. It will be used by the SPI driver to calculate the baud rate.

mips: Add Gardena Smart-Gateway board support

2018-09-23T12:27:51+00:00

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.

mips: Add LinkIt Smart 7688 support

2018-09-23T12:27:19+00:00

The LinkIt Smart 7688 modules have a MT7688 SoC with 128 MiB of RAM
and 32 MiB of flash (SPI NOR).

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

mips: Add basic MediaTek MT7620/88 support

2018-09-22T19:18:33+00:00

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.

MIPS: cache: remove config option CONFIG_SYS_MIPS_CACHE_MODE

2018-09-22T19:04:10+00:00

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.

MIPS: cache: make index base address configurable

2018-09-22T19:02:03+00:00

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).
