global: Convert simple_strtoul() with hex to hextoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 16 in each call. Add a new hextoul() function and update the code to use it. Add a proper comment to simple_strtoul() while we are here. Signed-off-by: Simon Glass

image-fdt: save no-map parameter of reserve-memory

2021-06-07T14:48:40+00:00

Save the 'no-map' information present in 'reserved-memory' node to allow correct handling when the MMU is configured in board to avoid speculative access. This binding is defined in doc/device-tree-bindings/reserved-memory/reserved-memory.txt Additional properties: ... no-map (optional) - empty property - Indicates the operating system must not create a virtual mapping of the region as part of its standard mapping of system memory, nor permit speculative access to it under any circumstances other than under the control of the device driver using the region.

lib: optee: migration optee_copy_fdt_nodes for OF_LIVE support

2021-04-12T18:25:31+00:00

The optee_copy_fdt_nodes is only used to copy op-tee nodes of U-Boot device tree (from gd->fdt_blob when OF_LIVE is not activated) to external device tree but it is not compatible with OF_LIVE. This patch migrates all used function fdt_ functions to read node on old_blob to ofnode functions, compatible with OF_LIVE and remove this parameter "old_blob". The generated "device tree" is checked on stm32mp platform with OF_LIVE activated. Signed-off-by: Patrick Delaunay

cmd: fdt: skip board specific fixup using env variable

2021-02-24T21:51:48+00:00

Sometimes it is useful to boot OS with already fixed-up device tree. Check for env variable 'skip_board_fixup' before calling ft_board_setup(). Current behaviour is unchanged, additionally user can set skip_board_fixup to 1 to skip the fixup. Signed-off-by: Wasim Khan

image: Adjust the workings of fit_check_format()

2021-02-16T03:31:52+00:00

At present this function does not accept a size for the FIT. This means that it must be read from the FIT itself, introducing potential security risk. Update the function to include a size parameter, which can be invalid, in which case fit_check_format() calculates it. For now no callers pass the size, but this can be updated later. Also adjust the return value to an error code so that all the different types of problems can be distinguished by the user.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

cmd: Fixup DT to pass PStore Ramoops parameters

2020-10-14T15:16:34+00:00

To simplify configuration and keep synchronized the PStore/Ramoops between U-Boot and the Linux kernel, this commit dynamically adds the Ramoops parameters defined in the U-Boot session to the Device Tree.

optee: copy FDT OP-TEE related nodes before generic FDT changes

2020-09-30T15:31:13+00:00

Move call to optee_copy_fdt_nodes() introduced by commit 6ccb05eae01b before generic changes in kernel FDT so that platform specific changes are not overridden by the changes made by this function.

find dtb in android boot image with header version 2 during bootm

2020-07-29T01:30:39+00:00

This patch is about bootm process, android boot image and device tree. Android 10 updates the boot image header to version 2, which includes a section to store the device tree blob (DTB) image. include/android_image.h has updated the struct andr_img_hdr, but not used in bootm process. This patch avoid reporting "Device tree not found or missing FDT support" when bootm a correctly constructed android boot image. Signed-off-by: chenshuo
