sunxi: h616: (really) lower SPL stack address to avoid BROM data

2023-12-06T23:08:37Z

When using the USB OTG FEL mode on the Allwinner H616, the BootROM stores some data at the end of SRAM C. This is also the location where we place the initial SPL stack, so it will overwrite this data. We still need the BROM code after running the SPL, so should leave that area alone. Interestingly this does not seem to have an adverse effect, I guess on the "way out" (when we return to FEL after the SPL has run), this data is not needed by the BROM, for just the trailing end of the USB operation. However this is still wrong, and we should not clobber BROM data. Lower the SPL stack address to be situated right below the swap buffers we use in sunxi-fel: that should be out of the way of everyone else. This obsoletes a previous commit (eb53e7743c8f) with the same name: that one was changing the address in an *unused* macro in sunxi_common.h, so the previous patch didn't have any effect at all.

sunxi: add Allwinner R528/T113 SoC support

2023-10-22T22:41:52Z

This adds the remaining code bits to teach U-Boot about Allwinner's newest SoC generation. This was introduced with the RISC-V based Allwinner D1 SoC, which actually shares a die with the ARM cores versions called R528 (BGA, without DRAM) and T113s (QFP, with embedded DRAM). This adds the new Kconfig stanza, using the two newly introduced symbols for the new SoC generation and pincontroller. It also adds the new symbols to the relavent code places, to set all the hardcoded bits directly. We need one DT override: The ARM core version of the DT specifies the CPUX watchdog as "reserved", which means it won't be recognised by U-Boot. Override this in our generic sunxi-u-boot.dtsi, to let U-Boot pick up this watchdog, so that the generic reset driver will work. Signed-off-by: Andre Przywara

sunxi: introduce NCAT2 generation model

2023-10-22T22:41:46Z

Allwinner seems to typically stick to a common MMIO memory map for several SoCs, but from time to time does some breaking changes, which also introduce new generations of some peripherals. The last time this happened with the H6, which apart from re-organising the base addresses also changed the clock controller significantly. We added a CONFIG_SUN50I_GEN_H6 symbol back then to mark SoCs sharing those traits. Now the Allwinner D1 changes the memory map again, and also extends the pincontroller, among other peripherals. To mark this generation of SoCs, add a CONFIG_SUNXI_GEN_NCAT2 symbol, this name is reportedly used in the Allwinner BSP code, and prevents us from inventing our own name. Add this new symbol to some guards that were already checking for the H6 generation, since many features are shared between the two (like the renovated clock controller). This paves the way to introduce a first user of this generation. Signed-off-by: Andre Przywara Tested-by: Samuel Holland

fs: ext4: Fix building ext4 in SPL if write is enabled

If EXT4_WRITE is enabled, write capabilities will be compiled into SPL, but not CRC16. Add an option to enable CRC16 to avoid linker errors. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

spl: Rename SYS_SPL_ARGS_ADDR to SPL_PAYLOAD_ARGS_ADDR

Rename this so that SPL is first, as per U-Boot convention. Also add PAYLOAD_ since this is where in memory the parameters for the payload have been stored. Signed-off-by: Simon Glass

spl: Use CONFIG_SPL... instead of CONFIG_..._SPL_...

Kconfigs: Correct default of "0" on hex type entries

2023-08-09T13:21:42Z

It is not a parse error to have a default value of "0" for a "hex" type entry, instead of "0x0". However, "0" and "0x0" are not treated the same even by the tools themselves. Correct this by changing the default value from "0" to "0x0" for all hex type questions that had the incorrect default. Fix one instance (in two configs) of a default of "0" being used on a hex question to be "0x0". Remove the cases where a defconfig had set a value of "0x0" to be used as the default had been "0".

spl: remove duplicate SPL_MD5 option

There is another SPL_MD5 option defined in lib/Kconfig. Renaming SPL_MD5_SUPPORT introduced duplicate option with different description. As for now FIT and hash algorithm options are not related to each others, removing a duplicate option seems OK.
