mpc85xx: relocate code in non-SPL build

2023-10-28T13:17:55Z

When building a non-SPL image, relocation is needed. This patch restores the old behaviour before commit b35316fb67cb ("Convert CONFIG_SPL_INIT_MINIMAL et al to Kconfig") was only defined if CONFIG_SPL_BUILD was defined. Fixes: b35316fb67cb ("Convert CONFIG_SPL_INIT_MINIMAL et al to Kconfig") Signed-off-by: Martin Fäcknitz

Use the new SPL/TPL/VPL_SYS_MALLOC_F symbols to determine whether the malloc pool exists. Signed-off-by: Simon Glass Reviewed-by: Sean Anderson

Kconfigs: Correct default of "0" on hex type entries

2023-08-09T13:21:42Z

It is not a parse error to have a default value of "0" for a "hex" type entry, instead of "0x0". However, "0" and "0x0" are not treated the same even by the tools themselves. Correct this by changing the default value from "0" to "0x0" for all hex type questions that had the incorrect default. Fix one instance (in two configs) of a default of "0" being used on a hex question to be "0x0". Remove the cases where a defconfig had set a value of "0x0" to be used as the default had been "0".

powerpc: Fix flush_cache() speed regression

2023-07-14T19:21:08Z

Flushing kernel image after decompression was taking 113 milliseconds with U-boot 2022.10. With U-boot 2023.01 and 2023.04, flushing the same amount of memory takes approx 1.5 seconds. With U-boot 2023.07-rc6, it takes 6.5 seconds. powerpc flush_cache() function used to call WATCHDOG_RESET() after flushing every cacheline. At that time WATCHDOG_RESET() was light so the operation was almost seamless. But commit 29caf9305b6 ("cyclic: Use schedule() instead of WATCHDOG_RESET()") replaced WATCHDOG_RESET() by schedule() and that started to hurt with U-boot 2022.10. And in U-boot 2023.07-rc6 that's even worse after commit 26e8ebcd7cb ("watchdog: mpc8xxx: Make it generic"). In the meantime commit 729c1fe656 ("powerpc: introduce CONFIG_CACHE_FLUSH_WATCHDOG_THRESHOLD") gives us the opportinity to only call schedule() every given chunk of data instead of every cacheline. As explained in that commit there is no point in pinging the watchdog after every cacheline flush, so lets define a sensible default chunk size of 4k which matches to size of a page on most powerpc platforms. With that new default threshold, the culprit flushing performed after kernel image decompression now takes 85 milliseconds on a powerpc 8xx.
