2025-06-18Merge patch series "list.h/treewide: get rid of no-op prefetch()"Tom Rini
Rasmus Villemoes <ravi@prevas.dk> says: While looking through list.h, I saw that the regular list_* helpers (and one of the hlist_* ones) still contain the prefetch() that was removed in linux 14 years ago. It doesn't do anything, but makes the macros harder to read, so get rid of it, and the fallback, no-op definition that they relied on. That requires removing a few uses outside list.h as well. checkpatch warns about some whitespace issues in list.h, but as I've copied whole kerneldoc+#define blocks directly from the linux kernel, I think it's better to just accept that so that we don't introduce needless diffs. The "macro argument reuse" arguments should also be ignored, as e.g. the "member" arguments are obviously always just bare identifiers, and the "pos" arguments must be assigned to multiple times.

2022-07-13mips: add support for noncached_alloc()Weijie Gao
This patch adds support for noncached_alloc() which was only supported by ARM platform. Unlike the ARM platform, MMU is not used in u-boot for MIPS. Instead, KSEG is provided to access uncached memory. So most code of this patch is copied from cache.c of ARM platform, with only two differences: 1. MMU is untouched in noncached_set_region() 2. Address returned by noncached_alloc() is converted using KSEG1ADDR() Reviewed-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com> Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>

We move the SYS_CACHE_SHIFT_N options from arch/arm/Kconfig to arch/Kconfig, and introduce SYS_CACHE_SHIFT_4 to provide a size of 16. Introduce select statements for other architectures based on current usage. For MIPS, we take the existing arch-specific symbol and migrate to the generic symbol. This lets us remove a little bit of otherwise unused code.

2020-07-18mips: reloc: Change R_MIPS_NONE to catch pre-reloc BSS usageStefan Roese
This patch changes the R_MIPS_NONE define from 0 to a magic value. This makes it possible to better detect any forbidden pre-relocation usage of BSS variables, as they are often zero'ed and then relocation is stopped too early. Additionally the error message is improved to also print the faulting address. This helps finding the root-cause for this breakage by comparing this address with the values in System.map. This patch helps a lot when working on pre-relocation code, like the Octeon DDR init code, where such variables have hit me multiple times now.

2020-04-27mips: add a mtmips-specific field to architecture-specific global dataWeijie Gao
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.
