MIPS: Make CONFIG_SYS_DCACHE_LINE_SIZE int, not hex

2016-06-10T10:27:37Z

For consistency with the other cache-related Kconfig entries & the values actually set by boards, make CONFIG_SYS_DCACHE_LINE_SIZE an int entry instead of a hex entry. Signed-off-by: Paul Burton Fixes: 372286217f05 ("MIPS: Split I & D cache line size config")

MIPS: Split I & D cache line size config

2016-05-31T07:44:24Z

Allow L1 Icache & L1 Dcache line size to be specified separately, since there's no architectural mandate that they be the same. The [id]cache_line_size functions are tidied up to take advantage of the fact that the Kconfig entries are always present to simply check them for zero rather than needing to #ifdef on their presence.

MIPS: Move cache sizes to Kconfig

2016-05-31T07:44:24Z

Move details of the L1 cache line sizes & total sizes into Kconfig, defaulting to 0. A new CONFIG_SYS_CACHE_SIZE_AUTO Kconfig entry is introduced to allow platforms to select auto-detection of cache sizes, and it defaults to being enabled if none of the cache sizes are set by the configuration (ie. sizes are all the default 0), and code is adjusted to #ifdef on that rather than on the definition of the sizes (which will always be defined even if 0).

malta: Allow MIPS64 builds

2016-05-31T07:38:11Z

Both real Malta boards & emulators that mimic Malta (eg. QEMU) can support MIPS64 CPUs. Allow MIPS64 builds of U-Boot for such boards, which enables the user to make use of the whole 64 bit address space. Signed-off-by: Paul Burton

malta: Use device model & tree for UART

2016-05-25T23:34:13Z

Make use of device model & device tree to probe the UART driver. This is the initial step in bringing Malta up to date with driver model, and allows for cleaner handling of the different I/O addresses for different system controllers by specifying the ISA bus address instead of a translated memory address.

malta: Support MIPS32r6 configurations

2016-05-20T23:36:39Z

Both real Malta boards & QEMU's Malta emulation can feature MIPS32r6 CPUs. Allow building U-Boot for such systems by selecting CONFIG_SUPPORTS_CPU_MIPS32_R6 for Malta. Signed-off-by: Paul Burton

MIPS: Support for targetting MIPSr6

2016-05-20T23:36:39Z

Add support for targetting MIPS32r6 & MIPS64r6 systems, in the same way that we currently select release 1 or release 2 targets. MIPSr6 is not entirely backwards compatible with earlier releases of the architecture. Some instructions are encoded differently, some are removed, some are reused, so it is not practical to run U-Boot built for earlier revisions on a MIPSr6 system. Update their Kconfig help text to reflect that. Signed-off-by: Paul Burton

MIPS: Simplify CONFIG_SYS_CPU values

2016-05-20T23:36:39Z

Rather than having the values for CONFIG_SYS_CPU depend upon each architecture revision, have them depend upon the more general CONFIG_CPU_MIPS32 & CONFIG_CPU_MIPS64 which in turn depend upon the architecture revisions. This is done in preparation for adding MIPSr6 support, which would otherwise need to introduce new cases here. Signed-off-by: Paul Burton
