====== PowerPC Book-E ======
This page was used to collect notes and keep track of tasks and timelines while the Book-E supports is being integrated and perfected.

These changes have been integrated into %%FreeBSD%%.

You can find some instructions that one person followed to get their e500 based eval board booting at [[WarnerLosh/Eval8540Boot|WarnerLosh/Eval8540Boot]].

===== Perforce branch =====

===== Outstanding work =====

^ Description ^ Status ^ Owner ^ Comments ^
| Unified machine-specific headers | Done: frame.h, hid.h, kdb.h, pcb.h, pcpu.h | marcel | To do: pmap.h, psl.h, pte.h, sf_buf.h, spr.h, tlb.h, trap.h, vmparam.h |
| Refactor code into sharp separation of core, %%SoC%% and platform (board) areas. |  | raj |  |
| Rework kstack0 proximity. | Done. | raj | Include Peter's suggestions on early switching to kstack just before mi_startup() |
| RTC on MPC8555CDS (DS1553) | Done. | raj | requires LBC driver |
| tsec(4): refactor sys/dev/if_tsec.c into the core driver part and the bus attachment; import advanced features: polling, interrupt coalescing; man page | Done. | raj |
| loader(8): de-hard code kernel load address (env var?) |  | raj |  |
| Refactor pmap, so that cpu-specific routines are clearly separated from generic %%BookE%% MMU operation; this way different %%BookE%% variations and revisions (e500v1/v2, ppc440) can have low-level routines according to their specifics (different kind and number of MMU assist registers etc.) |  | raj |  |
| Get USB to work on the MPC85xxCDS | in progress | marcel | Need support for cascaded i8259 |
| Add support for remote GDB |  |  | Check for section named .PPC.EMB.apuinfo in kernel and switch to the %%BookE%% register definition |
| Integrate LBC, CFI drivers | Done. |  |  |
