Hi,
thanks for all the patches.
If tested them on P1020 WLAN Rev D and found USB failing if,
- the usb chipset at 23000 stays in dts or [lockup during boot]
- usb is not loaded statically [won't recognize the usb bus]
Further, booting fails if the free_space mapping is in dts [lockup
during boot],
the freescale kernel has a slightly different dtsi file (no nand,
smaller nor)
so I changed that (works fine).
The RTC DS1307 needs RTC_CLASS and I2C to be set, so I added that.
Further, I enabled and testet kexec - works fine.
Additionally, I copied parts of the freescale linux kernel config over,
that looked like they mit benefit without interfering. This enables DMA,
for example. Already explained CONFIG_HIGHMEM.
I did not test the MMC interface.
Please find attached my modifications on top of your patch set.
Regards,
M. Braun

Subject: [PATCH] Fixups for P1020WLAN
Working on P1020WLAN support.
* get full memory working using CONFIG_HIGHMEM
* get usb host support working by removing second usb entry from dtsi file
(freescale takes same approach in the dev kit)
Further, the ehci_hcd module must be statically linked into the kernel,
otherwise the chipset won't be detected.
* enable kexec
* add some more freescale default options as they did test them with 2.6.32
This makes the rtc appear, for example.
