mips: mtmips: add two reference boards for mt7621

2022-07-13T21:03:37Z

The mt7621_rfb board supports integrated giga PHYs plus one external giga PHYs. It also has up to 512MiB DDR3, 16MB SPI-NOR, 3 mini PCI-e x1 slots, SDXC and USB. The mt7621_nand_rfb board is almost the same as mt7621_rfb board, but it uses NAND flash and SDXC is not available.

mips: mtmips: add support for MediaTek MT7621 SoC

2022-07-13T21:03:37Z

This patch adds support for MediaTek MT7621 SoC. All files are dedicated for u-boot. The default build target is u-boot-mt7621.bin. The specification of this chip: https://www.mediatek.com/products/homenetworking/mt7621 Reviewed-by: Daniel Schwierzeck Signed-off-by: Weijie Gao

mips: add support for noncached_alloc()

2022-07-13T21:03:37Z

This patch adds support for noncached_alloc() which was only supported by ARM platform. Unlike the ARM platform, MMU is not used in u-boot for MIPS. Instead, KSEG is provided to access uncached memory. So most code of this patch is copied from cache.c of ARM platform, with only two differences: 1. MMU is untouched in noncached_set_region() 2. Address returned by noncached_alloc() is converted using KSEG1ADDR() Reviewed-by: Daniel Schwierzeck Signed-off-by: Weijie Gao

mips: add __image_copy_len for SPL linker script

2022-07-13T21:03:37Z

This patch adds __image_copy_len needed by TPL of MT7621 SoC. The __image_copy_len represents the binary blob size of both SPL/TPL binaries. To achieve this, __text_start/end are added for calculation. Reviewed-by: Daniel Schwierzeck Signed-off-by: Weijie Gao

mips: add more definitions for asm/cm.h

2022-07-13T21:03:37Z

This patch add more definitions needed for MT7621 initialization. MT7621 needs to initialize GIC/CPC and other related parts. Reviewed-by: Daniel Schwierzeck Signed-off-by: Weijie Gao

mips: add asm/mipsmtregs.h for MIPS multi-threading

2022-07-13T21:03:37Z

To be compatible with old u-boot used by lots of MT7621 devices, the u-boot needs to boot-up MT7621's all cores, and all VPES of each core. This patch adds asm/mipsmtregs.h from linux kernel which is need for boot-up VPEs. Reviewed-by: Daniel Schwierzeck Signed-off-by: Weijie Gao

This option will be used by Microblaze that's why move it to generic location to be able to use it. Signed-off-by: Michal Simek Link: https://lore.kernel.org/r/ceb39fa615cb5657b66a7b77bab99e86ca7a3346.1655299267.git.michal.simek@amd.com

linker_lists: Rename sections to remove . prefix

2022-06-23T16:58:18Z

Rename the sections used to implement linker lists so they begin with '__u_boot_list' rather than '.u_boot_list'. The double underscore at the start is still distinct from the single underscore used by the symbol names. Having a '.' in the section names conflicts with clang's ASAN instrumentation which tries to add redzones between the linker list elements, causing expected accesses to fail. However, clang doesn't try to add redzones to user sections, which are names with all alphanumeric and underscore characters. Signed-off-by: Andrew Scull Reviewed-by: Simon Glass
