# Raspberry Pi CM4 (BCM2711) - onboard eMMC A/B disk boot.
#
# wolfBoot drives the BCM2711 EMMC2 controller (Arasan SDHCI v3.0 @ 0xFE340000)
# to read GPT A/B image partitions from the onboard eMMC via update_disk.c, and
# boots the highest valid version with rollback.
#
# Transfer mode: SDHCI_SDMA_DISABLED forces PIO. The BCM2711 EMMC2 SDMA
# boundary-restart and cache coherency are not yet validated (same Arasan
# family as the Versal quirk); DISK_EMMC compiles in the PIO BRR-race
# workaround in src/sdhci.c. SDHCI_FORCE_CARD_DETECT: the onboard eMMC has no
# routed card-detect line.
#
# Bring-up: uncomment DEBUG_SDHCI (+ DEBUG_DISK / DEBUG_GPT) for verbose
# controller/partition tracing over the mini-UART console.
#
# For wolfCrypt FIPS 140-3, build with FIPS=1 pointing at a FIPS / FIPS-ready
# wolfSSL tree (NO_ARM_ASM required; entropy from the RNG200 TRNG). See
