Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

global: Make include

2024-05-06T21:07:48Z

This follows the example of RISC-V where includes directly as "gd" includes a reference to bd_info already and so the first must include the second anyhow. We then remove from all of the places which include references to "gd" an so have already. Signed-off-by: Tom Rini

powerpc: Remove and add needed includes

2024-05-06T21:05:04Z

Remove from all powerpc architecture files and when needed add missing include files directly. This typically involves using instead due to the difficult nested structure of the PowerPC includes themselves. Signed-off-by: Tom Rini

Revert "Merge patch series "pxe: Allow extlinux booting without CMDLINE enabled""

2024-04-18T14:29:35Z

As reported by Jonas Karlman this series breaks booting on some AArch64 platforms with common use cases. For now the best path forward is to revert the series. This reverts commit 777c28460947371ada40868dc994dfe8537d7115, reversing changes made to ab3453e7b12daef47b9e91da2a2a3d48615dc6fc.

Merge patch series "pxe: Allow extlinux booting without CMDLINE enabled"

2024-04-10T23:06:27Z

Simon Glass says: This series is the culmanation of the current line of refactoring series. It adjusts pxe to call the booting functionality directly rather than going through the command-line interface. With this is is possible to boot using the extlinux bootmeth without the command line enabled. It also updates fastboot to do a similar thing.

treewide: Make arch-specific bootm code depend on BOOTM

2024-04-10T23:04:25Z

Allow these functions to be compiled in when CONFIG_BOOTM is enabled, even if CONFIG_CMD_BOOTM is not. Signed-off-by: Simon Glass Acked-by: Angelo Dureghello

bootm: Adjust arguments of boot_os_fn

2023-12-21T21:07:52Z

Adjust boot_os_fn to use struct bootm_info instead of the separate argc, argv and image parameters. Update the handlers accordingly. Few of the functions make use of the arguments, so this improves code size slightly. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

ppc: Add a reset_cpu() function

2023-12-21T21:07:52Z

The current do_reset() is called from a command context. Add a function which can be used from anywhere, as is done on ARM. This is only needed if CONFIG_SYSRESET is disabled. Since there are lots of reset functions, this one actually just calls do_reset(). Future refactoring could correct this. Signed-off-by: Simon Glass

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.

Correct SPL uses of LMB

2023-02-10T12:41:39Z

This converts 9 usages of this option to the non-SPL form, since there is no SPL_LMB defined in Kconfig Signed-off-by: Simon Glass
