| 2014-10-01 | PCI/MSI/PPC: Remove arch_msi_check_device() | Alexander Gordeev | |
| Move MSI checks from arch_msi_check_device() to arch_setup_msi_irqs(). This makes the code more compact and allows removing arch_msi_check_device() from generic MSI code.

| 2014-05-01 | powerpc: Added PCI MSI support using the HSTA module | Alistair Popple | |
| 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.
