[U-Boot] [PATCH 01/14] mips: Add in_le32(), out_le32() etc IO accessor functions

[Stefan Roese]

in_le32() and out_le32() are needed for the bootcounter support.
So lets implement these accessor functions for MIPS as well.

[U-Boot] [PATCH 02/14] mips: mt76xx: lowlevel_init.S: Add missing memory controller reset in DDR init

[Stefan Roese]

This fixes an issue which has been noticed on the Gardena board, with
the watchdog enabled, where the watdchdog reset (after a system hang)
did result in reporting of 2.9 GiB and a hang after this. With this
patch applied the memory controller is correctly reset and initialized
again even after a watchdog reset.

[U-Boot] [PATCH 03/14] mips: mt76xx: Enable SYS_MIPS_CACHE_INIT_RAM_LOAD for cache init

[Stefan Roese]

Using CONFIG_SYS_MIPS_CACHE_INIT_RAM_LOAD should ensure that the cache
is initialized correctly (parity etc). Even though some issues are
still seen on the linkit and gardena MT7688 platforms, which could
be a result of a non-optimal cache configuration / setup.

I thought this doesn't really help? Also if you can't move
CONFIG_MIPS_CACHE_INDEX_BASE to some SRAM space, you need to run your
memory init code before the cache initialisation to have working DRAM
available. But this slows down the boot time.

- Enable MIPS_BOOT_CMDLINE_LEGACY
- Enable FIT support
- Enable ethernet support
- Enable SPI NOR and NAND support
- Change MTD_UBI_BEB_LIMIT to 22
- Enable MTD Support
- Enable GPIO support
- Enable watchdog support
- Enable bootcounter support
- Enable version variable
- Change max image size from 0x80000 to 0xa0000
- Change SYS_MALLOC_LEN to 16MiB (because of UBI/UBIFS)

[U-Boot] [PATCH 13/14] mips: mt76xx: linkit-smart-7688: Use ioremap_nocache to get address

[Stefan Roese]

Use the correct function to get the uncached address to access the SoC
registers.

[U-Boot] [PATCH 14/14] mips: mt76xx: linkit-smart-7688: Misc updates to dts/config/defconfig

[Stefan Roese]

These misc updates include the following changes:
- Change baudrate from 57600 to 115200
- Enable MIPS_BOOT_CMDLINE_LEGACY
- Enable FIT support
- Enable ethernet support
- Enable SPI support
- Enable GPIO support
- Change max image size from 0x40000 to 0x80000

A note about the baudrate change:

The original Mediatek U-Boot version used 57600 baud. Lets move to a
more common and faster speed of 115200 baud. And remove the "console="
property from the DT as its not needed.

Yes, thanks. Looks pretty identical. Please go ahead with this
one from Mario and my patch can be dropped from this series then.

Thanks,
