This commit does the same thing as Linux commit 33def8498fdd.
Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

Generally speaking BINMAN_FDT makes sense for OF_SEPARATE or OF_EMBED.
For the other OF_CONTROL methods, it's quite possible binman node is
not available as binman is invoked during the build phase instead of
runtime. Let's only turn it on for OF_SEPARATE or OF_EMBED by default.

Build error occurs when CONFIG_EFI_SECURE_BOOT or
CONFIG_EFI_CAPSULE_AUTHENTICATE is enabled,
because hash-checksum.c is not compiled.
Since hash_calculate() implemented in hash-checksum.c can be
commonly used aside from FIT image signature verification,
this commit itroduces HASH_CALCULATE option to decide
if hash-checksum.c shall be compiled.

Up to now we are stopping the EFI subsystem if a TPMv2 exists but the
protocol fails to install. Now that we've switched the config to 'default
y' the sandbox TPM fails, since it doesn't support all the required
capabilities of the protocol.
Not installing the protocol is not catastrophic. If the protocol fails
to install the PCRs will never be extended to the expected values, so
some other entity later in the boot flow will eventually figure it out
and take the necessary actions.
While at it fix a corner case were the user can see an invalid error
message when the protocol failed to install. We do have a tcg2_uninit()
which we call when the protocol installation fails. There are cases though
that this might be called before the configuration table is installed (e.g
probing the TPM for capabilities failed). In that case the user will see
"Failed to delete final events config table". So stop printing it since it's
not an actual failure , simply because the config table was never installed
in the first place.
In order to stop printing it make efi_init_event_log() and create_final_event()
cleanup themselves and only call tcg2_uninit() when the protocol installation
fails.

This is same issue as https://bugzilla.redhat.com/show_bug.cgi?id=1733817,
but that fix was wrongly partial reverted.
When reading a directory, EFI_BUFFER_TOO_SMALL should be returned when
the supplied buffer is too small, so a use-case is to call
EFI_FILE_PROTOCOL.Read() with *buffer_size=0 and buffer=NULL to
obtain the needed size before doing the actual read.
So remove the check only for directory reading, file reading already
do the check by itself.

Commit a479f103dc1c ("hash: Allow for SHA512 hardware implementations")
defined function definitions for hardware accelerated SHA384 and SHA512.
If CONFIG_SHA_HW_ACCEL=y, these functions are used.
We already have boards using CONFIG_SHA_HW_ACCEL=y but none implements the
new functions hw_sha384() and hw_sha512().
For implementing the EFI TCG2 protocol we need SHA384 and SHA512. The
missing hardware acceleration functions lead to build errors on boards like
peach-pi_defconfig.
Introduce a new Kconfig symbol CONFIG_SHA512_HW_ACCEL to control if the
functions hw_sha384() and hw_sha512() shall be used to implement the SHA384
and SHA512 algorithms.

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.

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.

Remove function invocations using the EFI_CALL macro for those
functions that do not have an EFI_ENTRY call in their definition. Such
functions can use u-boot api's which rely on u-boot global data(gd)
pointer. The Arm and RiscV architectures maintain a separate gd
pointer, one for u-boot, and a separate gd for the efi application.
Calling a function through the EFI_CALL macro changes the gd pointer
to that used for the efi application, with u-boot gd being
unavailable. Any function then trying to dereference u-boot's gd will
result in an abort.
Fix this issue by removing the EFI_CALL macro for all of such
functions which do not begin by an EFI_ENTRY function call.
