One kernel image is requested, however, we need to enable iram for performance improvement on mx53, and disable it on mx51 due to known issue. So use platform data to pass vpu iram disable/enable flag. And considering requested iram size also can be different per requirement, iram size is also set in platform data.

2011-03-16ENGR00140638 - EPDC fb: System may hang if entering suspend while updates activeDanny Nold
- Added signalling to ensure suspend call does not return until EPDC has powered down. - Fixed race condition in IST. The working buffer (WB) process for a new update may report collision with LUTs that complete and are processed and removed by the IST before the working buffer completes. When this occurs, the collision may wait (forever) for a LUT that has already completed. This was putting the update queues into a bad state, preventing the update pipe from being flushed out. Solved this by tracking all completed LUTs after the WB process begins, and then removing them from the collision mask once the WB completes. Signed-off-by: Danny Nold <dannynold@freescale.com>

2011-03-15staging: add ath6kl driver for AR6003 chipVipin Mehta
AR6003 is a single stream, SDIO based 802.11 chipset from Atheros optimized for mobile and embedded devices. ath6kl is a cfg80211 driver for AR6003 and supports both the station and AP mode of operation. Station mode supports 802.11 a/b/g/n with HT20 on 2.4/5GHz and HT40 only on 5GHz. Some of the other features include WPA/WPA2, WPS, WMM, WMM-PS, and BT coexistence. AP mode can be operated only in b/g mode with support for a subset of features mentioned above. The driver supports cfg80211 but comes with its own set of wext ioctls which have historically supported some of our customers with features like BT 3.0 and AP mode of operation. For further details, please refer to: http://wireless.kernel.org/en/users/Drivers/ath6kl The driver requires firmware that runs on the chip's network processor. The majority of it is stored in ROM. The binaries that are downloaded and executed from RAM are as follows: 1) Patch against the code in ROM for bug fixes and feature enhancements. 2) Code to copy the data from the OTP region of the memory into RAM. 3) Calibration file carrying board specific data. The above files need to be present in the directory '/lib/firmware/ath6k/AR6003/hw2.0/' for the driver to initialize the chip upon enumeration. The files can be downloaded from the link specified at the following location: http://wireless.kernel.org/en/users/Drivers/ath6kl#Download This driver is only provided in the interim while we work on the mac80211 replacement, ath6k. Once the mac80211 driver achieves feature parity with the ath6kl driver, the ath6kl will be deprecated and removed from staging.
