Hi,
Commit 5dca710a3d7703e41da0e9894f2d71f9e25bea6b http://lists.denx.de/pipermail/u-boot/2010-October/078600.html removed the two global routines reset_timer_masked() and get_timer_masked() from arch/arm/cpu/arm926ejs/at91/timer.c.
Both routines are still referenced in drivers/spi/atmel_dataflash_spi.c. As a result SPI DataFlash support fails to compile for AT91 boards.
This had been also reported by http://lists.denx.de/pipermail/u-boot/2011-January/085399.html http://lists.denx.de/pipermail/u-boot/2010-November/081287.html but the problem still exists in the master trunk and the at91 branch.
For a first test I simply added
void reset_timer_masked(void) { reset_timer(); }
ulong get_timer_masked(void) { return tick_to_time(get_ticks() - gd->timer_reset_value); }
to drivers/spi/atmel_dataflash_spi.c. All DataFlash functions seem to work with this. But I'm not sure if this is a proper replacement for the original code.
Regards,
Harald
