spi: dw: Add SoC-specific compatible strings

2020-12-18T10:46:37Z

This adds SoC-specific compatible strings to all users of the designware spi device. This will allow for the correct driver to be selected for each device. Where it is publicly documented, a compatible string for the specific device version has also been added. Devices without publicly-documented device versions include MSCC SoCs, and Arc Socs. All compatible strings except those for SoCFPGAs and some of the versioned strings have been taken from Linux. Since SSI_MAX_XFER_SIZE is determined at runtime, this is not strictly necessary. However, it is a good cleanup and brings things closer to Linux. Signed-off-by: Sean Anderson Tested-by Eugeniy Paltsev Reviewed-by: Jagan Teki

mips: octeon: tools: Add update_octeon_header tool

2020-11-30T17:32:09Z

Add a tool to update or insert an Octeon specific header into the U-Boot image. This is needed e.g. for booting via SPI NOR, eMMC and NAND. While working on this, move enum cvmx_board_types_enum and cvmx_board_type_to_string() to cvmx-bootloader.h and remove the unreferenced (unsupported) board definition.

mips: octeon: bootoctlinux: Use gd->ram_size instead of ram_get_info()

2020-11-30T17:31:56Z

Using ram_get_info() is complicated and does not work after relocation. Now that gd->ram_size holds the full RAM size, let's use it instead and remove the ram_get_size logic completely.

mips: octeon: Report full DDR size in dram_init() to gd->ram_size

2020-11-30T17:31:56Z

With this patch, gd->ram_size now holds to full RAM size detected by the DDR init code. It introduces the get_effective_memsize() function to report the maximum usable RAM size in U-Boot to the system instead.

mips: start.S: Add Octeon boot header compatibility

2020-11-30T17:31:56Z

Octeon has a specific boot header, when booted via SPI NOR, NAND or MMC. Here the only 2 instructions are allowed in the first few bytes of the image. And these instructions need to be one branch and a nop. This patch adds the necessary nop after the nop, to that the common MIPS image is compatible with this Octeon header. The tool to patch the Octeon boot header into the image will be send in a follow-up patch.

mips: octeon: Add bootoctlinux command

2020-10-07T18:25:58Z

Octeon needs a platform specific cmd to boot the Linux kernel, as specific parameters need to be passed and special handling for the multiple cores (SMP) is needed.
