Subject: [U-Boot] [PATCH v1 0/4] arm: socfgpa: support of-platdata
Date: Mon, 7 Jan 2019 22:14:19 +0100 [thread overview]
Message-ID: <20190107211423.10151-1-simon.k.r.goldschmidt@gmail.com> (raw)
This is an initial attempt to support OF_PLATDATA for socfpga gen5.
There are two motivations for this:
a) reduce code size to eventually support secure boot (where SPL has to
authenticate the next stage by loading/checking U-Boot from a FIT
image)
b) to support the cyclone 5 boot ROM's CRC check on the SPL in SRAM
(on warm-restart), all bytes to check need to be in one piece. With
OF_SEPARATE, this is not the case (.bss is between .rodata and the
DTB). Since OF_EMBEDDED has been discouraged, OF_PLATDATA seems to
be a good solution.
This series enables booting from MMC with OF_PLATDATA. Booting from SPI
does not yet work (I'm working on that, but it's tougher than expected).
Tested on the socrates board. To use it:
- use socfpga_socrates_defconfig
- disable CONFIG_SPL_SPI_FLASH_SUPPORT, CONFIG_SPL_SPI_SUPPORT and
CONFIG_SPL_DM_RESET (those don't work yet)
- enable CONFIG_DESIGNWARE_SERIAL (required for console)
Simon Goldschmidt (4):
arm: socfpga: imply SPL config instead of select
arm: socfpga: fix compiling with OF_PLATDATA
serial: add an of-platdata driver for "snps,dw-apb-uart"
mmc: socfpga: support of-platdata
