ARM: da850-evm: Unify config options with Kconfig
There are two options that are currently whitelisted, but they
are redundant, because there are not necessary since Kconfig options
exist to basically state the same thing.
CONFIG_DIRECT_NOR_BOOT and CONFIG_USE_NOR are both set together and
only used by the da850 when booting from NOR, however the only time
CONFIG_MTD_NOR_FLASH is configured is when booting from NOR. Since
NOR doesn't need SPL, the options for SPL can be moved to a check for
building SPL instead of checking for NOR.
This patch removes the checks for these two config options and unifies
the checks around the Kconfig option of CONFIG_MTD_NOR_FLASH.
Since this board is the only board that uses these two config options,
they can be removed from the whitelist table.

do not need the SPL to do the low level initializion because when

efi_loader: image_loader: add digest-based verification for signed image
In case that a type of certificate in "db" or "dbx" is
EFI_CERT_X509_SHA256_GUID, it is actually not a certificate which contains
a public key for RSA decryption, but a digest of image to be loaded.
If the value matches to a value calculated from a given binary image, it is
granted for loading.
With this patch, common digest check code, which used to be used for
unsigned image verification, will be extracted from
efi_signature_verify_with_sigdb() into efi_signature_lookup_digest(), and
extra step for digest check will be added to efi_image_authenticate().
efi_loader: image_loader: verification for all signatures should pass
A signed image may have multiple signatures in
- each WIN_CERTIFICATE in authenticode, and/or
- each SignerInfo in pkcs7 SignedData (of WIN_CERTIFICATE)
In the initial implementation of efi_image_authenticate(), the criteria
of verification check for multiple signatures case is a bit ambiguous
and it may cause inconsistent result.
With this patch, we will make sure that verification check in
efi_image_authenticate() should pass against all the signatures.
The only exception would be
- the case where a digest algorithm used in signature is not supported by
U-Boot, or
- the case where parsing some portion of authenticode has failed
In those cases, we don't know how the signature be handled and should
just ignore them.
Please note that, due to this change, efi_signature_verify_with_sigdb()'s
function prototype will be modified, taking "dbx" as well as "db"
instead of outputing a "certificate." If "dbx" is null, the behavior would
be the exact same as before.
The function's name will be changed to efi_signature_verify() once
current efi_signature_verify() has gone due to further improvement
in intermediate certificates support.
efi_loader: signature: fix a size check against revocation list
Since the size check against an entry in efi_search_siglist() is
incorrect, this function will never find out a to-be-matched certificate
and its associated revocation time in the signature list.
efi_loader: image_loader: retrieve authenticode only if it exists
Since the certificate table, which is indexed by
IMAGE_DIRECTORY_ENTRY_SECURITY and contains authenticode in PE image,
doesn't always exist, we should make sure that we will retrieve its pointer
only if it exists.
efi_loader: image_loader: add a check against certificate type of authenticode
UEFI specification requires that we shall support three type of
certificates of authenticode in PE image:
WIN_CERT_TYPE_EFI_GUID with the guid, EFI_CERT_TYPE_PCKS7_GUID
WIN_CERT_TYPE_PKCS_SIGNED_DATA
WIN_CERT_TYPE_EFI_PKCS1_15
As EDK2 does, we will support the first two that are pkcs7 SignedData.
Now that commit 3e57f879eee6 ("mtd: nand: raw: denali: Assert reset
before deassert") added the reset assertion, this code in the board
file is unneeded.
