I usually send the MMC pull-request on Mondays, the first day of the merge window. [...] Kind regards Uffe

I tested the full series on the following OMAP1 boards: ams-delta, nokia770, osk, palmte and sx1 (QEMU only). Apart from the earlyprintk breakage, everything seemed to work OK. A minor note, zImage grows about 50 KB with a minimal kernel config. This is not yet critical, there's still about 7% headroom on 770 to the 2 MB bootloader limit on my setup. Also the decompression time is approaching the hardcoded watchdog timeout... A.

Nice, thanks a lot for testing! > A minor note, zImage grows about 50 KB with a minimal kernel config.

I suspect that most of this is for the added devicetree code, and some more for the common-clk layer. For the omap1_defconfig, there is some hope to get part of the overhead back eventually by replacing board files with dts descriptions that are not part of the zImage itself, but it's unlikely to ever get smaller than it was.

I tested the current omap1-multiplatform-5.18 branch from mach-omap2 point of view, and things seem to work just fine for me. I don't currently have any omap1 hardware online to test with. For the patches, please feel free to add: Acked-by: Tony Lindgren <tony@atomide.com>

With the updated patch 26 also earlyprintk now works, so if you still update the patches, feel free to add for the whole series: Tested-by: Aaro Koskinen <aaro.koskinen@iki.fi> Thanks, A.

There is now an "omap1/multiplatform-prep" branch that is part of arm/multiplatform, and I hope to not have to rebase that. I also have an arm/multiplatform-late branch with the remaining contents.

From: Arnd Bergmann <arnd@arndb.de> This is the full series for converting OMAP1 to multiplatform, rebased from my 2019 attempt to do the same thing. The soc tree contains simpler patches to do the same for iop32x, ixp4xx, ep93xx and s3c24xx, which means we are getting closer to completing this for all ARMv5 platforms (I have patches for PXA, which is the last one remaining). Janusz already tested the branch separately and did the missing work for the common-clk conversion after my previous approach was broken. The fbdev, mmc and ASoC portion of Janusz' work already went into the corresponding maintainer tree, but I include them here for reference. Unless there are any objections, I would add the entire series to the for-next branch of the soc tree, but only send the first 36 patches early in the merge window. After everything else has made it in, I would rebase the last two patches and send them separately, which may or may not make it in the merge window.
