[U-Boot-Users] [PATCH 0/7] 86xx: New law setup and updated reginfo patchset
This patchset adds support for the new law setup method in fsl_law.c to 86xx. The existing platforms (mpc8641hpcn, mpc8610hpcd, and sbc8641d) are converted to use the new method. The old support is them removed.
A print_laws() function is then added to fsl_law.c, and then used to implement a rudimentary reginfo for 86xx.
The first 2 patches in this set supersede these 2 previous patches sent to the list:
mpc86xx: Rearrange start.S to allow use of new law code mpc86xx: Convert to using new law setup code
The new patches are the same, but with cleaned-up commit logs.
This patchset contains: 86xx: Rearrange the sequence in start.S for 86xx 86xx: Support new law setup and convert mpc8641 86xx: Convert mpc8610hpcd to new law setup method 86xx: Convert sbc8641d to use new law setup code 86xx: Remove old style law setup code for 86xx 86xx: Add print_laws function to fsl_law.c 86xx: Add reginfo command for mpc86xx
Cheers, Becky
* split the BAT initialization so that only 2 BATs (for the boot page and stack) are programmed very early on. The rest are initialized later. * Move other BAT setup, ccsrbar setup, and law setup later in the code after translation has been enabled.
These changes will facilitate the moving of law and BAT initialization to C code, and will aid with 36-bit physical addressing support.

This patchset adds support for the new law setup method in fsl_law.c to 86xx. The existing platforms (mpc8641hpcn, mpc8610hpcd, and sbc8641d) are converted to use the new method. The old support is them removed.
A print_laws() function is then added to fsl_law.c, and then used to implement a rudimentary reginfo for 86xx.
The first 2 patches in this set supersede these 2 previous patches sent to the list:
mpc86xx: Rearrange start.S to allow use of new law code mpc86xx: Convert to using new law setup code
The new patches are the same, but with cleaned-up commit logs.
This patchset contains: 86xx: Rearrange the sequence in start.S for 86xx 86xx: Support new law setup and convert mpc8641 86xx: Convert mpc8610hpcd to new law setup method 86xx: Convert sbc8641d to use new law setup code 86xx: Remove old style law setup code for 86xx 86xx: Add print_laws function to fsl_law.c 86xx: Add reginfo command for mpc86xx
Cheers, Becky
Becky,
I've picked up the entire set and applied it. I'll slate it for the _next_ merge window!
Thanks, jdl
