[PATCH 0/9] TI: AM654/J721e: Add support to boot from OSPI

[Vignesh Raghavendra]

This series adds support to boot from OSPI on TI's AM654 and J721e SoCs.
These EVMs have Micron MT35x flash and works in 1-1-8 mode.

[PATCH 1/9] drivers: Descend to drivers/soc unconditionally

[Vignesh Raghavendra]

Descend to drivers/soc directory unconditionally for SPL and U-Boot
builds. Individual drivers can have their own config to check what needs
to be built for SPL. There should be no increase in SPL code size
due to this change.

This is required on K3 SoCs to support DMA in SPL.

Populate address mapping entries in A53 MMU for 4 GB of MMIO space
reserved for providing MMIO access to multiple flash devices through
OSPI/HBMC IPs within FSS.

[PATCH 3/9] ARM: mach-k3: sysfw-loader: Use SPI memmapped addr when loading SYSFW

[Vignesh Raghavendra]

From: Lokesh Vutla <lokeshvutla@ti.com>

Since ROM configures OSPI controller to be in memory mapped mode in OSPI
boot, R5 SPL can directly pass the memory mapped pointer to ROM. With
this ROM can directly pull the SYSFW image from OSPI.

[PATCH 0/9] TI: AM654/J721e: Add support to boot from OSPI

Hi Vignesh,

we have some documentation in our TI tree regarding OSPI boot in the
board-specific readme files such as how to program the OSPI with the
different U-Boot artifacts, etc which is super helpful for a user.

Would you mind including this info into this series for both AM654x and
J721E?

Thanks, Andreas

Sure, thanks for pointing that out! Will include it as part of this
series if I have to respin because of any other comments, else will
submit a separate series updating the READMEs

This is causing build failures on hs configs. Can you fix it and repost?
