* [PATCH 43/61] 8xx: Always reset CPM if not using early console.
From: Scott Wood @ 2007-07-18 1:35 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20070718013137.GA15217@ld0162-tx32.am.freescale.net>
Some CPM devices conflict with each other, and the bootloader
may have initialized a conflicting device.

* [PATCH 37/61] cpm2: Rework 8272ads initialization, and eliminate init_fcc_ioports().
From: Scott Wood @ 2007-07-18 1:35 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20070718013137.GA15217@ld0162-tx32.am.freescale.net>
The mpc8272ads initialization is reworked to:
1. use cpm2_set_pin() and cpm2_clk_setup() instead of the hardcoded mess,
2. have a sane devtree binding for the BCSR,
3. set the BCSR bits needed for both ethernet ports to work,
4. support the early debug console, and
5. call of_platform_bus_probe(), for the forthcoming of-platform-ization
of the CPM drivers.
The init_fcc_ioports() call is no longer used. CPM-based 85xx
is now broken until I can get a test machine, unless U-boot properly
sets up the I/O ports.

* [PATCH 32/61] mpc82xx: Move PQ2 restart and halt functions out of mpc8272-specific code.
From: Scott Wood @ 2007-07-18 1:35 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20070718013137.GA15217@ld0162-tx32.am.freescale.net>
I renamed it from m82xx to pq2 because it won't work on the Integrated
Host Processor line of 82xx chips (i.e. 8240, 8245, and such).

It is not always the case that the SoC's first reg property points
to the beginning of the entire SoC block.

This provides a generic way for board code to set up CPM pins, rather
than directly poking magic values into registers.

In-Reply-To: <20070718013137.GA15217@ld0162-tx32.am.freescale.net>
The hardware adds one to the BRG value to get the divider, so it must
be subtracted by software.
