mips: cmd: go: Flush cache before jumping to app/image

2020-04-09T17:00:00Z

It has been noticed on MT7628/88 platforms, that booting the RAM image does not work reliably. Sometimes it works and sometimes not. Debugging showed that this "might" be a cache related issue as very strange errors occurred (e.g. output corrupted etc). This patch adds a cache flush for the complete SDRAM area to the go cmd before jumping to the entry point for the MIPS architecture. The complete area is flushed as we don't know at this point, how big the area of the "application" really is.

MIPS: allow override of flush_dcache_range()

2020-04-09T16:55:59Z

Useful in custom HW designs which have a need to flush dcache range in a completely non standard way. Signed-off-by: Alex Nemirovsky

common: Move hang() to the same header as panic()

2020-01-17T22:53:40Z

At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header. Signed-off-by: Simon Glass [trini: Migrate a few more files] Signed-off-by: Tom Rini

common: Move relocate_code() to init.h

2020-01-17T18:26:49Z

This is an init function so move it out of the common header. Avoid using the typedef so that we don't have to include the global_data header file. Also tidy up the function style in comments while we are here. Signed-off-by: Simon Glass

common: Move ARM cache operations out of common.h

2019-12-02T23:24:58Z

These functions are CPU-related and do not use driver model. Move them to cpu_func.h Signed-off-by: Simon Glass Reviewed-by: Daniel Schwierzeck Reviewed-by: Tom Rini

common: Move some cache and MMU functions out of common.h

2019-12-02T23:23:55Z

These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

MIPS: add compile time definition of L2 cache size

2019-10-25T15:20:43Z

If configuration is set to skip low level init, automatic probe of L2 cache size is not performed and the size is set to 0. Flushing or invalidating the L2 cache will fail in this case. Add a static configuration (SYS_DCACHE_LINE_SIZE) with default set to 0. Signed-off-by: Ramon Fried

arch: mips: Update initrd_start and initrd_end

2019-05-03T14:42:23Z

Microsemi SoC defines CONFIG_SYS_SDRAM_BASE to be 0x80000000, which represents the start of kseg0 and represents a virtual address. Meaning that the initrd_start and initrd_end point somewhere kseg0. When these parameters are passed to linux kernel through DT they are pointing somewhere in kseg0 which is a virtual address but linux kernel expects the addresses to be physical addresses(in kuseg) because it is converting the physical address to a virtual one. Therefore update the uboot to pass the physical address of initrd_start and initrd_end by converting them using the function virt_to_phys before setting up the DT.
