502d4577e2 Use the new gic option on all configs that need it. 2015-05-10 12:13:27 +00:00

e2a65d5cfa Add support for the uart classes to set their default register shift value. 
This is needed with the pl011 driver. Before this change it would default
to a shift of 0, however the hardware places the registers at 4-byte
addresses meaning the value should be 2.

This patch fixes this for the pl011 when configured using the fdt. The
other drivers have a default value of 0 to keep this a no-op.

b4fa4f6baa For some reason, all the arm bus_space functions that work with uint16 
values have armv4 in the name.  There's nothing armv4-special about them,
so just use the same sort of names as all the other functions.

7dd1b73c38 Make the GPIO children attach to the first unit available and not only to 
unit 0.

It seems that this 'simplification' was copied to all GPIO drivers in tree.

This fix a bug where a GPIO controller could fail to attach its children
(gpioc and gpiobus) if another GPIO driver attach first.

ad9a51105a Add the start of the ARM platform code. This is based on the PowerPC 
platform code, it is expected these will be merged in the future when the
ARM code is more complete.

Until more boards can be tested only use this with the Raspberry Pi and
rrename the functions on the other SoCs.

e825adc7a6 Eliminate irq_dispatch.S. Move the data items it contained into arm/intr.c 
and the functionality it provided into arm/exception.S.  Rename the main
irq handling routine from arm_handler_execute() to arm_irq_handler() to
make it more congruent with how other exception handlers are named, and
also update its signature to reflect what has long been reality: it is
passed just a trapframe pointer, no interrupt number argument.
