* x86: acpi: Support generation of the DBG2 tableSimon Glass2020-09-251-0/+64
| | | | | | | | | | | | Add an implementation of the DBG2 (Debug Port Table 2) ACPI table. Adjust one of the header includes to be in the correct order, before adding more. Note that the DBG2 table is generic but the PCI UART is x86-specific at present since it assumes an ns16550 UART. It can be generalised later if necessary.

* fdtdec: optionally add property no-map to created reserved memory nodeEtienne Carriere2020-09-222-3/+9
| | | | | | | | | | | | | | | | | | Add boolean input argument @no_map to helper function fdtdec_add_reserved_memory() to add or not "no-map" property for an added reserved memory node. Property no-map is used by the Linux kernel to not not map memory in its static memory mapping. It is needed for example for the| consistency of system non-cached memory and to prevent speculative accesses to some firewalled memory. No functional change. A later change will update to OPTEE library to add no-map property to OP-TEE reserved memory nodes.

| * lib: fdt: Fix fdtdec_setup_mem..() conversion to livetree APIMarek Vasut2020-09-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Repair incorrectly negated condition in the original patch which broke DT memory node parsing on everything which has more than one DT memory node, e.g. R-Car3. In case multiple valid memory nodes are present in the DT, the original patch would complete parsing cycle for the first memory node, then move on to the next one, identify it as a valid, and end the parsing. The fix is to invert the condition, to make the code behave as it did before the livetree conversion, so it would continue parsing the subsequent memory nodes as well.

| | | | | | | | | | | | | | | | | | | | | | | | | New function should be called from board dram_init() because it initialized gd->ram_base/ram_size. It finds the lowest available memory. On systems with multiple memory nodes finding out the first memory node by fdtdec_setup_mem_size_base() is not enough because this memory can be above actual U-Boot VA mapping. Currently only mapping till 39bit is supported (Full 44bit mapping was removed by commit 7985cdf74b28 ("arm64: Remove non-full-va map code")). If DT starts with the first memory node above 39bit address then system can be unpredictable. The function is available only when multiple memory bank support is enabled. Calling fdtdec_setup_memory_banksize() from dram_init() is not possible because fdtdec_setup_memory_banksize() is saving dram information to bd structure which is placed on stack but not initialized at this time. Also stack is placed at location setup in dram_init(). Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".
