2021-05-18lib: introduce HASH_CALCULATE optionMasahisa Kojima
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.

2021-05-18efi_loader: Don't stop EFI subsystem init if installing TCG2 failsIlias Apalodimas
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.

2021-05-18efi_loader: loosen buffer parameter check in efi_file_read_intPeng Fan
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.

2021-05-18hash: Kconfig option for SHA512 hardware accelerationHeinrich Schuchardt
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); ...

2021-04-22lmb: Add 2 config to define the max number of regionsPatrick Delaunay
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.

2021-04-17efi_loader: esrt: Remove incorrect invocations of EFI_CALL macroSughosh Ganu
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.
