NET: DW: fix regression for ARC boards

2019-10-07T17:23:49Z

The commit 642b80d256e ("net: designware: drop compatible altr, socfpga-stmmac") breaks designware ethernet for all ARC boards. It removes "altr, socfpga-stmmac" compatible from "drivers/net/designware.c" without changing compatible in the boards which use it. Fix that by adding "snps,arc-dwmac-3.70a" compatible string to "drivers/net/designware.c" and using it in ARC boards device tree. Signed-off-by: Eugeniy Paltsev

arc: libgcc: Import udivdi3 & udivmoddi4 to allow 64-bit division

2019-09-03T16:05:34Z

As reported by Kever here [1] we were unable to compile 64-bit division code due to missing definition of __udivdi3(). Import its implementation and __udivmoddi4() as its direct dependency from today's libgcc [2].

CONFIG_SPL_SYS_[DI]CACHE_OFF: add

2019-05-18T12:15:35Z

While converting CONFIG_SYS_[DI]CACHE_OFF to Kconfig, there are instances where these configuration items are conditional on SPL. This commit adds SPL variants of these configuration items, uses CONFIG_IS_ENABLED(), and updates the configurations as required.

CONFIG_SYS_[DI]CACHE_OFF: convert to Kconfig

2019-05-18T12:15:34Z

CONFIG_SYS_[DI]CACHE_OFF had been partially converted to Kconfig parameters; only for the ARC architecture. This patch turns these two parameters into Kconfig items everywhere else they are found. All of the include/configs/* and defconfig changes in this patch are for arm machines only. The Kconfig changes for arc, nds32, riscv, and xtensa have been included since these symbols are found in code under arch/{arc,nds32,riscv,xtensa}, however, no currently-defined include/configs/* or defconfigs for these architectures exist which include these symbols. These results have been confirmed with tools/moveconfig.py. Acked-by: Alexey Brodkin Signed-off-by: Trevor Woerner [trini: Re-migrate for a few more boards] Signed-off-by: Tom Rini

dts: switch spi-flash to jedec, spi-nor compatible

2019-04-12T05:24:27Z

There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot dts files. This compatible has been added in sf_probe, let use it. This patch switches to jedec,spi-nor when spi-flash is used in the DTS and DTSI files, and removed spi-flash when jedec,spi-nor is already present. The x86 dts are switched in a separate commit since it depends on a change in fdtdec.

ARC: cache: define CONFIG_SYS_CACHELINE_SIZE as ARCH_DMA_MINALIGN

2019-01-25T05:41:09Z

Even though we don't use CONFIG_SYS_CACHELINE_SIZE in ARC-specific code it is used a lot in different drivers for alignment purposes. So we define it and make much more drivers at least compilable for ARC. Signed-off-by: Alexey Brodkin

ARC: Fix iteration in arc_xx_version()

2019-01-25T05:40:53Z

"i" gets incremented before we're entering loop body and effectively we iterate from 1 to 8 instead of 0 to 7. This way we: a) Skip the first line of struct hs_versions b) Go over it and access memory beyond the structure Signed-off-by: Alexey Brodkin

Kconfig: Migrate BOUNCE_BUFFER

2019-01-19T14:49:26Z

The bounce buffer is used by a few drivers (most of the MMC drivers) to overcome limitations in their respective DMA implementation. This moves the configuration to Kconfig and makes it user-selectable (even though it will be a required feature to make those drivers work): the expected usage is for drivers depending on this to 'select' it unconditionally from their respective Kconfig (see follow-up patches). This commit includes a full migration using moveconfig.py to ensure that each commit compiles. To ensure bisectability we update dependencies of various drivers to now select BOUNCE_BUFFER when needed.
