Hello Andrew,
Le Mon, 2 Jul 2012 20:33:30 +0200,
Andrew Lunn <andrew@lunn.ch> a ?crit :

As per armada-370-xp.h:
#define ARMADA_370_XP_REGS_PHYS_BASE 0xd0000000
The physical address of the internal registers is 0xd0000000. It does
not seem to be configurable using the address decoding mechanism.
OMAP has some logic to handle this kind of problems, see
plat-omap/include/plat/uncompress.h. We can quite certainly overcome
this problem somehow.
Best regards,
Thomas
