Bug Description
If you boot the linaro beta image on qemu-maemo's beaglexm model:
qemu-maemo-
then during bootup there are a large number of warning messages:
omap_i2c_write: Bad register 0x000000ec
The DM37x TRM section 17.6.2 (HS I2C Registers) only lists registers at offsets from 0x00 to 0x54, so I think the model is correct that 0xEC is bogus. We should investigate what bit of the kernel is doing this and what it thinks it's doing.
