Hello Matthias,

Thanks for the nice work. The patches look mostly fine. I wonder that U-Boot ep93xx support has never made it to the mainline. Some comments about the patches inline.

Aren't the LED functions and thus the lowlevel_init board specific? I can imagine many custom boards do not have LEDs connected to these gpio pins.

I think it's better to add a

#ifdef CONFIG_ARCH_EP93XX
		/* the EP93xx expects to find the pattern 'CRUS' at
		 * 0x1000
		 */
		. = 0x1000;
		LONG(0x53555243) /* 'CRUS' */

#endif

to the generic linker script. We might have to revert this when we're heading to an ifdeffery here, but for now I think it's better be able to make changes to the linker script in only one file.

in late december i sent a (new) set of patches to the U-Boot mailing list. i still havn't received feedback, i suppose due to christmas, new year, ... my aim is to mainline ep93xx support, i am confident this will be accomplished soon.

Aren't the LED functions and thus the lowlevel_init board specific? I can imagine many custom boards do not have LEDs connected to these gpio pins.

custom board could do this, but probably shouldn't. the EP93xx explicitly 'reserves' specific GPIOs for a red and a green LED. these LEDs are used by the boot algorithm to give feed back before the bootloader is started.

please tell me if this convinces you to leave the LED functions and lowlevel_init in the SoC part or if you prefer moving them to the board directory.

I think it's better to add a

that's fine for me

thanks for your review!

Aren't the LED functions and thus the lowlevel_init board specific? I can imagine many custom boards do not have LEDs connected to these gpio pins.

custom board could do this, but probably shouldn't. the EP93xx explicitly 'reserves' specific GPIOs for a red and a green LED. these LEDs are used by the boot algorithm to give feed back before the bootloader is started.

Ah, I didn't know this. A good move from Cirrus that the software developer can rely on some debug LEDs.

Quoted 4 lines

please tell me if this convinces you to leave the LED functions and lowlevel_init in the SoC part or if you prefer moving them to the board directory.

I'm fine with the LEDs being available for all ep93xx then.

Something went wrong here, this seems to be a fixup patch, at least these hunks.
