* MIPS: Support dynamic I/O port base addressPaul Burton2016-02-01-34/+34
| | | | | | | | | | | | 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 <paul.burton@imgtec.com>
* MIPS: Remove SLOW_DOWN_IOPaul Burton2016-02-01-37/+3
| | | | | | | | | CONF_SLOWDOWN_IO is never set for any target, so remove the dead code in the SLOW_DOWN_IO macro. This is done in preparation for changes to mips_io_port_base which can be avoided in this path by removing it entirely. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* mips: cache: Bulletproof the code against cornercasesMarek Vasut2016-02-01-0/+8
| | | | | | | | | | | | | | | | | | | This patch makes sure that the flush/invalidate_dcache_range() functions can handle corner-case calls like this -- invalidate_dcache_range(0, 0, 0); This call is valid and is happily produced by USB EHCI code for example. The expected behavior of the cache function(s) in this case is that they will do no operation, since the size is zero. The current implementation though has a problem where such invocation will result in a hard CPU hang. This is because under such conditions, where the start_addr = 0 and stop = 0, the addr = 0 and aend = 0xffffffe0 . The loop will then try to iterate over the entire address space, which in itself is wrong. But iterating over the entire address space might also hit some odd address which will cause bus hang. The later happens on the Atheros MIPS. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Daniel Schwierzeck <daniel.schwierzeck@gmail.com> Cc: Hans de Goede <hdegoede@redhat.com>

| | | | | | | | | | | | | | | | 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 <daniel.schwierzeck@gmail.com>

Always relocate ramdisk and FDT in step 'bootm prep' because the generic bootm code does this only for legacy uImage's. Move the step 'bootm cmdline' to 'bootm prep' because the Linux kernel parameters rd_start and rd_size have to be initialized after the relocation of the ramdisk.
