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.

ARC: Improve identification of ARC cores

2018-12-03T11:26:18Z

1. Try to guess a ARC core template that was used i.e. not just name a core family but something more menaingful like "ARC HS38", "ARC EM11D" etc. We do it checking availability of the key differentiation features like: - Caches (we actually only check for L1 I$ fpr simplicity) - XY-memory - DSP extensions etc. 2. Identify ARC subsystems 3. Print core clock frequency Signed-off-by: Alexey Brodkin

ARC: Don't use COMMON section for global not-initialized variables

2018-10-15T10:35:17Z

By default GCC puts global non-initialized variables in COMMON section. And we used to ignore existence of COMMON section in our linker scripts though smart LD silently appended it right after .bss. And the problem here is variables from COMMON section even though require zeroing in run-time were not zeroed as they were placed right after __bss_end symbol. It was a pure luck we never faced serious problem due to this, but now it is fixed. Now as for some other architectures we'll just force GCC to put those global variables in normal .bss section. This solution is much nicer than adding COMMON section to each and every linker script. Signed-off-by: Alexey Brodkin

ARC: make generic print_cpuinfo() weak

2018-10-12T12:14:40Z

This allows board to override print_cpuinfo() because they might know better which ARChitect template was used. This way we may not only derive base architecture type and version but more meaningful things like "ARC EM7D" instead of simple "ARC EM", "ARC HS36" instead of "ARC HS". Signed-off-by: Alexey Brodkin
