[U-Boot] Latest u-boot-atmel git hangs on AVR32 board

[Mark Jackson <mpfj-list@mimc.co.uk>]

Hi

Our MIMC200 board has been using 2009.08 for some time, so I thought I would take a look at the
latest git version to keep our boards more up-to-date.

I have checked out the u-boot-atmel branch, and done:-

$ make mimc200_config
$ make

Everything compiles, but when I try the image, I only get:-

U-Boot 2011.06-rc2-02816-g5f2e176 (Jun 13 2011 - 12:50:29)

U-Boot code: 00000000 -> 00012668  data: 0001ae38 -> 00050840
LCD: Frame buffer allocated at preset 0x10600000
VMR table @ 0x11fca7f4

I have traced through the code to see where things stop, and it seems to be in:-

arch/avr32/cpu/at32ap700x/mmu.c

void mmu_init_r(unsigned long dest_addr)
{
	...
	printf("VMR table @ 0x%08x\n", vmr_table_addr);

 	/* Enable paging */
puts("a");
	sysreg_write(MMUCR, SYSREG_BF(DRP, 1) | SYSREG_BF(DLA, 1)
			| SYSREG_BIT(MMUCR_S) | SYSREG_BIT(M) | SYSREG_BIT(E));
puts("b");
}

I get the "VMR table ..." string, as well as "a", but I never get "b".

Can anyone help ?

Regards
Mark
