* | powerpc: Added PCI MSI support using the HSTA module | Alistair Popple | 2014-05-01 | 1 | -0/+215 |
The PPC476GTR SoC supports message signalled interrupts (MSI) by writing to special addresses within the High Speed Transfer Assist (HSTA) module. This patch adds support for PCI MSI with a new system device. The DMA window is also updated to allow access to the entire 42-bit address range to allow PCI devices write access to the HSTA module.
