- Subject: PXA27x support
The attached patch adds (some) support for PXA27x processors to the
pxa2x0 HAL. Limited to some extra register #defines and support for the
extra interrupts on the PXA27x.
A new CDL option (CYGOPT_HAL_ARM_XSCALE_PXA2X0_VARIANT) to the pxa2x0
HAL to select which variant of the pxa2xx family to support, either
PXA25x (the default) or PXA27x.
Additionally, hal_delay_us() will busy-wait for the correct period of
time if it takes longer than 1 timer tick per loop to read the counter
register.
