| 2015-12-05 | Paul Boddie | changeset files shortlog graph | Write through uncached memory to test memory access. This avoids page faults but means that the TLB is not being set up properly. Still, ERL can now be cleared. | stage2-non-pic |

| 2015-12-03 | Paul Boddie | changeset files shortlog graph | Changed the payload to load at 0x80000000, positioning the vectors at the base of the payload, with the start of the main program at 0x80001000. Changed the boot script to actually work with USB Boot, given possible problems with the provided stage1 payload (and nonsensical xbboot/usbboot behaviour). | stage2-non-pic |
