Adding support for BeagleBoard.
ArmPkg - Supoprt for ARM specific things that can change as the architecture changes. Plus semihosting JTAG drivers. EmbeddedPkg - Generic support for an embeddded platform. Including a light weight command line shell. BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open source USB stack (Our internal stack works fine). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9518 6f19259b-4bc3-4df7-8a09-765794883524

Abstraction for hardware based interrupt routine
|
||||
|
||||
On non IA-32 systems it is common to have a single hardware interrupt vector
|
||||
and a 2nd layer of software that routes the interrupt handlers based on the
|
||||
interrupt source. This protocol enables this routing. The driver implementing
|
||||
this protocol is responsible for clearing the pending interrupt in the
|
||||
interrupt routing hardware. The HARDWARE_INTERRUPT_HANDLER is responsible
|
||||
for clearing interrupt sources from individual devices.
