dm: core: Add address translation in fdt_get_resource

2021-04-29T10:23:39+00:00

Today of_address_to_resource() is called only in
ofnode_read_resource() for livetree support and
fdt_get_resource() is called when livetree is not supported.

The fdt_get_resource() doesn't do the address translation
so when it is required, but the address translation is done
by ofnode_read_resource() caller, for example in
drivers/firmware/scmi/smt.c::scmi_dt_get_smt_buffer() {
...
	ret = ofnode_read_resource(args.node, 0, &resource);
	if (ret)
		return ret;

	faddr = cpu_to_fdt32(resource.start);
	paddr = ofnode_translate_address(args.node, &faddr);
...

The both behavior should be aligned and the address translation
must be called in fdt_get_resource() and removed for each caller.

efi_loader: capsule: return a correct error code at find_boot_device()

2021-04-24T04:53:40+00:00

In case of failure at efi_get_variable_int("BootOrder"), we should
skip examining boot option variables and return an appropriate error
code which is the one the function returned.

efi: Fix ESRT refresh after Capsule update

2021-04-24T04:53:40+00:00

Indicated by Coverity Scan CID 331147

The ESRT was being refreshed in situations where the UpdateCapsule
procedure failed. In that scenario:

1) the ESRT refresh was superfluous.
2) a failed ESRT refresh return code overwrites the UpdateCapsule error
return code.

This commit ensures that the ESRT is only refreshed when the
UpdateCapsule performs successfully.

efi_loader: simplify tcg2_create_digest()

2021-04-24T04:53:40+00:00

Bumping the digest list count, for all supported algorithms,  can be
calculated outside of the individual switch statements.  So let's do that
for every loop iteration instead and simplify the code a bit.

lmb: Add 2 config to define the max number of regions

2021-04-22T18:09:45+00:00

Add 2 configs CONFIG_LMB_MEMORY_REGIONS and CONFIG_LMB_RESERVED_REGIONS
to change independently the max number of the regions in lmb
library.

When CONFIG_LMB_USE_MAX_REGIONS=y, move the lmb property arrays to
struct lmb and manage the array size with the element 'max' of struct
lmb_region; their are still allocated in stack.

When CONFIG_LMB_USE_MAX_REGIONS=n, keep the current location in
struct lmb_region to allow compiler optimization.

Increase CONFIG_LMB_RESERVED_REGIONS is useful to avoid lmb errors in
bootm when the number of reserved regions (not adjacent) is reached:
+ 1 region for relocated U-Boot
+ 1 region for initrd
+ 1 region for relocated linux device tree
+ reserved memory regions present in Linux device tree.

The current limit of 8 regions is reached with only 5 reserved regions
in DT.

lmb: add a max parameter in the struct lmb_region

2021-04-22T18:09:45+00:00

Add a max parameter in lmb_region struct to handle test
in lmb_add_region without using the MAX_LMB_REGIONS
define.

This patch allows to modify these size independently for
memory of reserved regions in the next patches.
