Add more flags for the fpexc register from the ARM1176JZF-S Manual
Initialise fpscr to a sane value when we create the pcb. This sets NaNs to
be the default NaN and for denormalised numbers to be flushed to zero.
VFP fixes/cleanups for ARM11:
* Save the required VFP registers on context switch. If the exception bit
is set we need to save and restore the FPINST register, and if the fp2v
bit is also set we need to save and restore FPINST2.
* Move saving and restoring the floating point control registers to C.
* Clear the fpexc exception and fp2v flags on a floating-point exception.
* Signal a SIGFPE if the fpexc exception flag is set on an undefined
instruction. This is how the ARM core signals to software there is a
floating-point exception.
Add Cortex-A15 cpu id revisions.
Exynos/Arndale...
- Merge SoC-common parts
- Enable iicbus device
- Directly call kmem_alloc_contig to allocate framebuffer memory
and pass VM_MEMATTR_UNCACHEABLE (no-cache, no-buffer).
This fixes screen refreshing problem when data is updated too slowly.
- Add support for keyboard used in Samsung Chromebook (ARM machine)
Support covers device drivers for:
- Interrupt Combiner
- gpio/pad, External Interrupts Controller (pad)
- I2C Interface
- Chrome Embedded Controller
- Chrome Keyboard
- Use new gpio dev class in EHCI driver
- Expand device tree information
- Release i2c bus on detach.
