fsl-layerscape/soc.c: do not destroy bootcmd environment

2024-02-08T02:45:32Z

When an XXX_BOOTCOMMAND isn't defined, the result is that bootcmd is set to some random memory content. Fix it so that the function does nothing in that case and leaves the bootcmd environment unmodified. Signed-off-by: Mike Looijmans Reviewed-by: Dan Carpenter

mxs: Fix VDDx brownout interrupt disable/enable

2023-12-20T18:00:47Z

Incorrect registers HW_POWER_VDDIOCTRL, HW_POWER_VDDACTRL and HW_POWER_VDDDCTRL are used in the current code to disable/enable brownout interrupts in 'mxs_power_set_vddx()'. Change register to HW_POWER_CTRL which contains brownout interrupt enable bits ENIRQ_VDDIO_BO, ENIRQ_VDDA_BO and ENIRQ_VDDD_BO.

arm: mxs: Clear CPSR V bit to activate low vectors

2023-12-13T18:33:21Z

The MXS starts with CPSR V bit set, which makes the CPU jump to high vectors in case of an exception. Those high vectors are located at 0xffff0000, which is where the BootROM exception table is located as well. U-Boot should handle exceptions on its own using its own exception handling code, which is located at 0x0, i.e. at low vectors. Clear the CPSR V bit, so that the CPU would jump to low vectors on exception instead, and therefore run the U-Boot exception handling code. Signed-off-by: Marek Vasut Reviewed-by: Fabio Estevam

Merge patch series "bootm: Refactoring to reduce reliance on CMDLINE (part A)"

2023-12-13T16:51:53Z

To quote the author: It would be useful to be able to boot an OS when CONFIG_CMDLINE is disabled. This could allow reduced code size. Standard boot provides a way to handle programmatic boot, without scripts, so such a feature is possible. The main impediment is the inability to use the booting features of U-Boot without a command line. So the solution is to avoid passing command arguments and the like to code in boot/ A similar process has taken place with filesystems, for example, where we have (somewhat) separate Kconfig options for the filesystem commands and the filesystems themselves. This series starts the process of refactoring the bootm logic so that it can be called from standard boot without using the command line. Mostly it removes the use of argc, argv and cmdtbl from the internal logic. Some limited tidy-up is included, but this is kept to smaller patches, rather than trying to remove all #ifdefs etc. Some function comments are added, however. A simple programmatic boot is provided as a starting point. This work will likely take many series, so this is just the start. Size growth with this series for firefly-rk3288 (Thumb2) is: arm: (for 1/1 boards) all +23.0 rodata -49.0 text +72.0 This should be removed by: https://source.denx.de/u-boot/custodians/u-boot-dm/-/issues/11 but it is not included in this series as it is already large enough. No functional change is intended in this series. Changes in v3: - Add a panic if programmatic boot fails - Drop RFC tag Changes in v2: - Add new patch to adjust position of unmap_sysmem() in boot_get_kernel() - Add new patch to obtain command arguments - Fix 'boot_find_os' typo - Pass in the command name - Use the command table to provide the command name, instead of "bootm"

arm: x86: Drop discarding of command linker-lists

2023-12-13T16:51:24Z

Since we can now cleanly disable CMDLINE when needed, drop the rules which discard the command code. It will not be built in the first place. Signed-off-by: Simon Glass Reviewed-by: Tom Rini Reviewed-by: Ilias Apalodimas

Revert "arm64: Use FEAT_HAFDBS to track dirty pages when available"

2023-11-17T16:58:26Z

This reverts commit 6cdf6b7a340db4ddd008516181de7e08e3f8c213. This is part of a series trying to make use of the arm64 hardware features for tracking dirty pages. Unfortunately this series causes problems for the AC5/AC5X SoCs. Having exhausted other options the consensus seems to be reverting this series is the best course of action.
