[U-Boot] QSPI XIP boot on am437x

Hi,

With commit 7ae8350f67eea("ti: armv7: Move SPL SDRAM init to the right place, drop unused CONFIG_SPL_STACK") QSPI XIP boot appears to be broken on AM437x SK EVM.

Following UART initialization code (as indicated by TODO) causes the XIP boot failure.

In arch/arm/cpu/armv7/am33xx/board.c: @@ -275,9 +275,9 @@ void s_init(void) #if defined(CONFIG_NOR_BOOT) || defined(CONFIG_QSPI_BOOT) /* TODO: This does not work, gd is not available yet */ gd->baudrate = CONFIG_BAUDRATE; serial_init(); gd->have_console = 1; #endif

I was able to boot successfully from QSPI by commenting out the above code. But, could you suggest me what needs to be done as part of TODO in order to get QSPI XIP boot working?

Thanks!
