common: Drop linux/bitops.h from common header

Move this uncommon header out of the common header. Signed-off-by: Simon Glass

common: Drop net.h from common header

2020-05-18T21:33:31Z

Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass

mips: add a mtmips-specific field to architecture-specific global data

2020-04-27T18:29:33Z

SoCs of mtmips can use different CPU frequencies depending on the HW/SW configurations. For example mt7628 uses 580MHz clock if the input xtal frequency is 40MHz, and 575MHz clock if the xtal is 25MHz. Upon cold boot the CPU uses the xtal frequency directly. So hardcoding the timer frequency (half of the CPU frequency) in CONFIG_SYS_MIPS_TIMER_FREQ is not a good idea for this case. This patch adds a mtmips-specific field timer_freq to arch_global_data. This field will be used later in mtmips-specific get_tbclk() to provide accurate timer frequency in different boot stage.

mips: add support to restore exception vector base before booting linux

2020-04-27T18:29:33Z

In U-Boot the exception vector base will be moved to top of memory, to be used to display register dump when exception occurs. But some old linux kernel does not honor the base set in CP0_EBASE. A modified exception vector base will cause kernel crash. This patch adds an option to enable reset exception vector base to its previous value, or a user configured value before booting linux kernel.

dma-mapping: add for all architectures

2020-02-20T07:09:54Z

To avoid "asm/dma-mapping.h: No such file or directory" error, we need something. Signed-off-by: Masahiro Yamada

mips: Add SPL header

Add header with SPL boot mode and type definitions. Cc: Daniel Schwierzeck Signed-off-by: Paul Burton Signed-off-by: Marek Vasut

MIPS: Allow to prefetch and lock instructions into cache

2018-12-19T14:23:01Z

This path add a new helper allowing to prefetch and lock instructions into cache. This is useful very early in the boot when no RAM is available yet. Signed-off-by: Gregory CLEMENT

MIPS: move create_tlb() in an proper header: mipsregs.h

2018-12-19T14:23:01Z

Export create_tlb() as an inline function in mipsregs.h. It allows to remove the declaration of the function from the board files. Then it will allow also to use this function very early in the boot when the stack is not usable. Signed-off-by: Gregory CLEMENT

MIPS: remove local_irq_[save|restore] from CP0 macros

2018-12-19T14:23:01Z

With moving write_on_tlb() to arch/mips/include/asm/mipsregs.h there are now compiler warnings when some generic code includes asm/io.h. This happens for example when enabling OF live tree. Signed-off-by: Daniel Schwierzeck

MIPS: drop asm/const.h

2018-11-20T12:08:15Z

Commit 86f21c96f467368 (mips: Use common _AC macro now.) removed the _AC definition from const.h. All other macros defined in const.h are not used anywhere, and there is now no user of this header. Remove this header. Cc: Daniel Schwierzeck Signed-off-by: Baruch Siach Reviewed-by: Tom Rini Reviewed-by: Daniel Schwierzeck Signed-off-by: Stefan Roese
