spl: fit: Also record architecture in /fit-images

2021-06-23T07:48:36+00:00

On ARM64 secure OS can run as 64bit or 32bit that's why it is necessary to record information about architecture that other code can read it and properly pass it to TF-A and start in 64bit or 32bit mode. Signed-off-by: Michal Simek Reviewed-by: Simon Glass

common: fit: Update board_fit_image_post_process() to pass fit and node_offset

2021-06-11T11:04:52+00:00

board_fit_image_post_process() passes only start and size of the image, but type of the image is not passed. So pass fit and node_offset, to derive information about image to be processed. Signed-off-by: Lokesh Vutla Reviewed-by: Tom Rini Signed-off-by: Tero Kristo

sysinfo: Require that sysinfo_detect be called before other methods

2021-05-04T11:57:18+00:00

This has the uclass enforce calling detect() before other methods. This allows drivers to cache information in detect() and perform (cheaper) retrieval in the other accessors. This also modifies the only instance where this sequencing was not followed. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

spl: fit: Support loading FPGA images from list of "loadables"

2021-04-14T19:23:01+00:00

Commit 4afc4f37c70e ("doc: FIT image: Clarify format and simplify syntax") and delegated FPGA images to be added via the list of "loadables" in lieu of the "fpga" property. Now actually implement this in code. Note that the "compatible" property is ignored for the time being, as implementing "compatible" loading is beyond the scope of this change. However, "u-boot,fpga-legacy" is accepted without warning. Signed-off-by: Alexandru Gagniuc

spl: fit: Warn if FIT contains "fpga" property in config node

2021-04-14T19:23:01+00:00

Commit 4afc4f37c70e ("doc: FIT image: Clarify format and simplify syntax") requires that FPGA images be referenced through the "loadables" in the config node. This means that "fpga" properties in config nodes are deprecated. Given that there are likely FIT images which use "fpga", let's not break those right away. Print a warning message that such use is deprecated, and give users a couple of releases to update their Signed-off-by: Alexandru Gagniuc

spl: fit: Move FPGA loading code to separate functions

2021-04-14T19:23:01+00:00

The FPGA loading code in spl_simple_fit_read() can easily be separated from the rest of the logic. It is split into two functions instead of one because spl_fit_upload_fpga() is used in a subsequent patch. Signed-off-by: Alexandru Gagniuc Reviewed-by: Simon Glass

spl: fit: Don't overwrite previous loadable if "load" is missing

2021-04-14T19:23:01+00:00

spl_load_fit_image() will try to load an image at the address given in the "load" property. Absent such property, it uses image_info->load_addr Correct use of this is demonstrated in spl_fit_append_fdt(), which resets the 'load_addr' before each spl_load_fit_image() call. On the other hand loading "loadables" loop in spl_load_simple_fit() completely ignores this. It re-uses the same structure, but doesn't reset load_addr. If loadable [i] does not have a "load" property, its load address defaults to load_addr, which still contains the address of loadable [i - 1]. A simple solution is to treat NULL as an invalid load address. The caller can set load_addr = 0 to request an abort if the "load" property is absent.

spl: Convert spl_fit to work with sandbox

2021-03-12T14:57:31+00:00

At present this casts addresses to pointers so cannot work with sandbox. Update the code to use map_sysmem() instead. As part of this change, the existing load_ptr is renamed to src_ptr since it is not a pointer to load_addr. It is confusing to use a similar name for something that is not actually related. For the alignment code, ALIGN() is used instead of open-coded alignment. Add a comment to the line that casts away a const. Use a (new) load_ptr variable to access memory at address load_addr.

spl: fit: Load devicetree when a Linux payload is found

2021-02-18T00:46:43+00:00

When a FIT config specifies a devicetree, we should load it, no questions asked. In the case of the "simple" FIT loading path, a difficulty arises in selecting the load address of the FDT. The default FDT location is right after the "kernel" or "firmware" image. However, if that is an OP-TEE image, then the FDT may end up in secure DRAM, and not be accessible to normal world kernels. Although the best solution is to be more careful about the FDT address, a viable workaround is to only append the FDT after a u-boot or Linux image. This is identical to the previous logic, except that FDT loading is extended to IH_OS_LINUX images. Signed-off-by: Alexandru Gagniuc
