Wires the new wolfBoot_gunzip inflater into the FIT image-loading path
and adds initramfs (ramdisk) extraction with DTB /chosen fixup so a
single signed FIT can carry kernel, DTB, and rootfs.
GZIP path
---------
* fit_load_image_ex(out_max) added; fit_load_image kept as a wrapper.
* When a subimage carries compression="gzip", inflate straight to the
FIT-declared load address, then verify the FIT hash-1 subnode
(sha256 / sha384 if available) for defense in depth on top of the
outer wolfBoot signature. The compression property is now read
unconditionally so a build without WOLFBOOT_GZIP can warn and fail
closed instead of silently memcpy-ing compressed bytes as if they
were raw.
* fit_verify_hash propagates wc_InitSha256 / wc_Sha256Update /
wc_Sha256Final return codes (and the SHA-384 equivalents) - any
non-zero return is treated as a verification failure so a misbehaving
backend cannot silently degrade to a no-op.
* GZIP=1 is the new default in the FIT-using example configs (zynqmp,
zynqmp_sdcard, polarfire_mpfs250, polarfire_mpfs250_qspi,
versal_vmk180, versal_vmk180_sdcard); set GZIP=0 to opt out.
Ramdisk path
------------
* fit_find_images() gains a ramdisk out-arg and fdt_fixup_initrd()
writes /chosen/linux,initrd-{start,end} as 64-bit big-endian cells.
* update_disk.c and update_ram.c load the FIT ramdisk node (under
WOLFBOOT_FIT_RAMDISK) and patch the loaded DTB. Compressed (gzip)
ramdisks reuse the same fit_load_image_ex() decompress path.
* RAMDISK=1 build switch defines WOLFBOOT_FIT_RAMDISK;
WOLFBOOT_LOAD_RAMDISK_ADDRESS is plumbed through tools/config.mk ->
Makefile sed -> include/target.h.in. Defaults to 0; when 0 the
ramdisk stays at whatever fit_load_image returned.
* hal/zynq.c and hal/versal.c bump fdt_totalsize headroom from 512 to
768 bytes to fit the new linux,initrd-{start,end} entries.
* config/examples/zynqmp_sdcard.config gains a commented-out opt-in
block (RAMDISK=1, WOLFBOOT_LOAD_RAMDISK_ADDRESS=0x40000000, alt
LINUX_BOOTARGS) so a single config file covers both rootfs-on-disk
and FIT-bundled-initramfs flows.
Builds against the existing master configs are byte-identical when
GZIP=0 and RAMDISK is unset.
* Fixes to support wolfBoot native make and gcc-arm cross compiler. ZD 18159
* Adjust wolfBoot linker script to not use 0 base, instead use end of DDR - 1MB.
* Fixed QSPI bare-metal driver for multi-sector and read return code.
* Fixed issue with Xilinx XMSS IMAGE_HEADER_SIZE in documentation. It should be 5000 bytes.
* Performance optimizations for QSPI:
- Allow configuration of SPI clock.
- Improve GSPI FIFO TX/RX fill.
* Added support for FAST_MEMCPY that supports an aligned 32-bit.
* Added Flattened uImage Tree (FIT) image (FDT format).
* Added Aarch64 support for FDT fixups.
* Added Aarch64 startup to support EL2 with cache/MMU.
* Added documentation about exception levels
* Moved zynqmp registers to header.
* Fix printf uart_writenum "buf" len.
* Updated fdt-parser to support saving off larger data images.
* Fixed PPC spin table based on ePAPR 1.1.
* Added flattened device tree (FDT) support. Setting required FDT fields per ePAPR 1.1.
* Added Frame Manager microcode upload.
* Fixed CPLD and setting QE clock.
* Added support for setting logical device numbers and updated device tree.
* Fixed QUICC Engine base address (was incorrect, should be 0x140000).
* Fixed "cpu-release-addr" to use 64-bit value.
* Added secondary cached boot page.
* Added L2 cache support to multi-core.
* Added flattened device tree parser tool for testing (`make fdt-parser` and `tools/fdt-parser/fdt-parser`).
* Added checks for FDT header.
* Added automated test case for NXP T1024 FDT.
