[PATCH 0/2] SPARC64: switch to MMIO NVRAM access
by Mark Cave-Ayland 19 Jan '15

19 Jan '15

Happy New Year everyone! This patchset is a minor rework of Artyom's patchset last year which when combined with the corresponding QEMU patches fixes NVRAM/RTC access under sun4u. The modifications I've made to the orignal patches are: 1) Change NVRAM_BASE from 0x1000 to 0x2000 NetBSD has a bug where it incorrectly calculates the size of the VA mapping if the NVRAM straddles a page. Fix this by setting the offset to 0x2000 instead of 0x1000 to ensure the NVRAM mapping is aligned to an 8K page. 2) Fixup the eeprom node properties With the introduction of the new PCI interrupt map, the format of the ebus reg property has changed. Hence I've altered the second patch in the series to bring it in line with the existing ebus devices.
