* pico-imx6ul: convert ethernet function to DM_ETHWig Cheng2020-08-182-53/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | - Remove pinmux definition from pico-imx6ul.c - Enable NET_RANDOM_ETHADDR for temporary solution, because micrel_ksz8xxx driver does not support DM_ETH yet, so cannot read MAC address directly.

* ARM: imx: Add support for switching primary/secondary boot mode to bmodeMarek Vasut2020-08-174-7/+21
| | | | | | | | | | | | | | | The i.MX6/i.MX7 is capable of booting a secondary "redundant" system image in case the primary one is corrupted. The user can force this boot mode as well by explicitly setting SRC GPR10 bit 30. This can be potentially useful when upgrading the bootloader itself. Expose this functionality to the user.

| * efi_loader: signature: correct a behavior against multiple signaturesAKASHI Takahiro2020-08-143-88/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under the current implementation, all the signatures, if any, in a signed image must be verified before loading it. Meanwhile, UEFI specification v2.8b section 32.5.3.3 says, Multiple signatures are allowed to exist in the binary’s certificate table (as per PE/COFF Section “Attribute Certificate Table”). Only one hash or signature is required to be present in db in order to pass validation, so long as neither the SHA-256 hash of the binary nor any present signature is reflected in dbx. This patch makes the semantics of signature verification compliant with the specification mentioned above.

| * efi_loader: variable: fix secure state initializationAKASHI Takahiro2020-08-131-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under the new file-based variable implementation, the secure state is always and falsely set to 0 (hence, the secure boot gets disabled) after the reboot even if PK (and other signature database) has already been enrolled in the previous boot. This is because the secure state is set up *before* loading non-volatile variables' values from saved data. This patch fixes the order of variable initialization and secure state initialization.

| * efi_loader: signature: rework for intermediate certificates supportAKASHI Takahiro2020-08-135-213/+188
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In this commit, efi_signature_verify(with_sigdb) will be re-implemented using pcks7_verify_one() in order to support certificates chain, where the signer's certificate will be signed by an intermediate CA (certificate authority) and the latter's certificate will also be signed by another CA and so on. What we need to do here is to search for certificates in a signature, build up a chain of certificates and verify one by one. pkcs7_verify_one() handles most of these steps except the last one. pkcs7_verify_one() returns, if succeeded, the last certificate to verify, which can be either a self-signed one or one that should be signed by one of certificates in "db". Re-worked efi_signature_verify() will take care of this step. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a bug fix; Setting an authenticated variable may fail due to a memory corruption in the authentication. A temporary buffer will, if needed, be allocated to parse a variable's authentication data, and some portion of buffer, specifically signer's certificates, will be referenced by efi_signature_verify(). So the buffer should be kept valid until the authentication process is finished. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Tested-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

| * common/board_f: make sure to call fix_fdt() before reserve_fdt()Pragnesh Patel2020-08-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | There may be a chance that board specific fix_fdt() will change the size of FDT blob so it's safe to call reserve_fdt() after fix_fdt() otherwise global data (gd) will overwrite with FDT blob values.
