MIPS: Support dynamic I/O port base address

2016-02-01T21:13:25Z

The existing mips_io_port_base variable isn't suitable for use early during boot since it will be stored in the .data section which may not be writable pre-relocation. Fix this by moving the I/O port base address into struct arch_global_data. In order to avoid adding this field for all targets, make this dependant upon a new Kconfig entry CONFIG_DYNAMIC_IO_PORT_BASE. Malta is the only board which sets a non-zero I/O port base, so select this option only for Malta. Signed-off-by: Paul Burton

MIPS: kconfig: add option for MIPS_L1_CACHE_SHIFT

2016-01-16T20:06:46Z

Add Kconfig symbol for L1 cache shift like the kernel does. The value of CONFIG_SYS_CACHELINE_SIZE is not a reliable source for ARCH_DMA_MINALIGN anymore, because it is optional on MIPS. If CONFIG_SYS_CACHELINE_SIZE is not defined by a board, the cache sizes are automatically detected and ARCH_DMA_MINALIGN would be set to 128 Bytes. The default value for CONFIG_MIPS_L1_CACHE_SHIFT is 5 which corresponds to 32 Bytes. All current MIPS boards already used that value. While on it, fix the Malta board to use a value of 6 like the kernel port does. Signed-off-by: Daniel Schwierzeck

MIPS: Kconfig: optimize gcc -march and -mtune setup

2016-01-16T20:06:46Z

Move setup of -march to arch/mips/Makefile and follow the design on ARM. Also add a possibility to chose specific CPU tune options. Signed-off-by: Wills Wang Signed-off-by: Daniel Schwierzeck

Move default y configs out of arch/board Kconfig

2015-06-26T02:17:55Z

Some archs/boards specify their own default by pre-defining the config which causes the Kconfig system to mix up the order of the configs in the defconfigs... This will cause merge pain if allowed to proliferate. Remove the configs that behave this way from the archs. A few configs still remain, but that is because they only exist as defaults and do not have a proper Kconfig entry. Those appear to be: SPIFLASH DISPLAY_BOARDINFO Signed-off-by: Joe Hershberger [trini: rastaban, am43xx_evm_usbhost_boot, am43xx_evm_ethboot updates, drop DM_USB from MSI_Primo81 as USB_MUSB_SUNXI isn't converted yet to DM] Signed-off-by: Tom Rini

arch: Make board selection choices optional

2015-05-12T22:10:02Z

By making the board selections optional, every defconfig will include the board selection when running savedefconfig so if a new board is added to the top of the list of choices the former top's defconfig will still be correct.

MIPS: implement device-tree handover to Linux kernel

2015-04-24T10:15:34Z

Add device-tree handover to Linux kernel conforming with MIPS UHI [1]. Register $a0 will be set to the reserved value -2. The address of the device-tree blob will be stored as KSEG0 address in $a1. $a2 and $a3 are set to zero. [1] http://prplfoundation.org/wiki/MIPS_documentation Signed-off-by: Daniel Schwierzeck

MIPS: allow systems to skip loads during cache init

2015-01-29T11:55:01Z

Current MIPS systems do not require that loads be performed to force the parity of cache lines, a simple invalidate by clearing the tag for each line will suffice. Thus this patch makes the loads & subsequent second invalidation conditional upon the CONFIG_SYS_MIPS_CACHE_INIT_RAM_LOAD option, and defines that for existing mips32 targets. Exceptions are malta where this is known to be unnecessary, and qemu-mips where caches are not implemented. Signed-off-by: Paul Burton Cc: Daniel Schwierzeck

MIPS: replace $(CPU) with Kconfig symbols

2015-01-21T13:06:04Z

Conditionally set head-y and lib-y with boolean Kconfig symbols for selected CPU. This deprecates the usage of the $(CPU) variable. Signed-off-by: Daniel Schwierzeck
