Introduce <alg>_LEGACY kconfig for legacy hash implementations. sha256.o should depend on SHA256 kconfig only but not SUPPORT_EMMC_RPMB, SHA256 should be selected when SUPPORT_EMMC_RPMB is enabled instead. `IS_ENABLED` or `CONFIG_IS_ENABLED` is not applicable here, since including <linux/kconfig.h> causes undefined reference on schedule() with sandbox build, as <linux/kconfig.h> includes <generated/autoconf.h> which enables `CONFIG_HW_WATCHDOG` and `CONFIG_WATCHDOG` but no schedule() are defined in sandbox build, Thus we use `#if defined(CONFIG_MBEDTLS_LIB_CRYPTO)` instead.

2024-10-14mbedtls: add mbedtls into the build systemRaymond Mao
Port mbedtls with adapted libc header files. Add mbedtls default config header file. Optimize mbedtls default config by disabling unused features to reduce the target size. Add mbedtls kbuild makefile. Add Kconfig skeleton and config submenu entry for selecting crypto libraries between mbedtls and legacy ones. Add the mbedtls include directories into the build system. Port u-boot hash functions as MbedTLS crypto alternatives and set it as default. Subsequent patches will separate those Kconfigs into pairs of _LEGACY and _MBEDTLS for controlling the implementations of legacy crypto libraries and MbedTLS ones respectively. The motivation of moving and adapting *INT* macros from kernel.h to limits.h is to fulfill the MbedTLS building requirement. The conditional compilation statements in MbedTLS expects the *INT* macros as constant expressions, thus expressions like `((int)(~0U >> 1))` will not work. Prerequisite ------------ This patch series requires mbedtls git repo to be added as a subtree to the main U-Boot repo via: $ git subtree add --prefix lib/mbedtls/external/mbedtls \ https://github.com/Mbed-TLS/mbedtls.git \ v3.6.0 --squash Moreover, due to the Windows-style files from mbedtls git repo, we need to convert the CRLF endings to LF and do a commit manually: $ git add --renormalize . $ git commit Signed-off-by: Raymond Mao <raymond.mao@linaro.org>

Backport from the upstream Linux kernel commit c2cf7e25eb2a3c915a420fb8ceed8912add7f36c "mtd: rawnand: brcmnand: Add support for getting ecc setting from strap" Note: the upstream kernel introduces a new bool brcmnand_get_sector_size_1k() function because the int version in U-Boot has been removed in Linux. I kept the old int-returning version that is already in U-Boot as we depend on that in other code. BCMBCA broadband SoC based board design does not specify ecc setting in dts but rather use the SoC NAND strap info to obtain the ecc strength and spare area size setting.

Backport from upstream Linux commit 60177390fa061c62d156f4a546e3efd90df3c183 "mtd: rawnand: brcmnand: Fix mtd oobsize" brcmnand controller can only access the flash spare area up to certain bytes based on the ECC level. It can be less than the actual flash spare area size. For example, for many NAND chip supporting ECC BCH-8, it has 226 bytes spare area. But controller can only uses 218 bytes. So brcmand driver overrides the mtd oobsize with the controller's accessible spare area size. When the nand base driver utilizes the nand_device object, it resets the oobsize back to the actual flash spare aprea size from nand_memory_organization structure and controller may not able to access all the oob area as mtd advises. This change fixes the issue by overriding the oobsize in the nand_memory_organization structure to the controller's accessible spare area size.
