This patch set is providing initial support for QCA AR9344 SoC.
So far it provides PLL and DDR2 initialization.
UART and SPI controller should work as well.
Following variants was tested:
- load PBL to SRAM over JTAG for PLL and DDR2 initialization or configure
them with JTAG.
- load and start complete zbarebox.bin or barebox.bin to previously configured
DDR2 RAM. Both variants are working.
- start zbarebox.bin from SPI flash
JTAG config for OpenOCD can be found here:
https://github.com/olerem/openocd/commits/ar9344
or maybe later upstrean in OpenOCD directly.

QCA AR9331 and QCA AR9344 have some similar part but different uart engines.
We need this flag to provide common debug_ll support.

According to the documentation:
"The AR9344 is a highly integrated and feature-rich IEEE 802.11n 2x2 2.4/5 GHz
System-on-a-Chip (SoC) for advanced WLAN platforms.
It includes a MIPS 74Kc processor, PCI Express 1.1 Root Complex and Endpoint
interfaces, five port IEEE 802.3 Fast Ethernet Switch with MAC/PHY,
one MII/RMII/RGMII interface, one USB 2.0 MAC/PHY, and external memory
interface for serial Flash, SDRAM, DDR1 or DDR2, I2S/SPDIF-Out audio interface,
SLIC VOIP/PCM interface, two UARTs, and GPIOs that can be used for LED
controls or other general purpose interface configurations.
The AR9344 supports 802.11n operations up to 144 Mbps for 20 MHz and 300 Mbps
for 40 MHz respectively, and 802.11a/b/g data rates.
Additional features include Maximal Likelihood (ML) decoding, Low-Density
Parity Check (LDPC), Maximal Ratio Combining (MRC), Tx Beamforming (TxBF), and
On-Chip One-Time Programmable (OTP) memory."

This provides low level initialization of pll and ddr2. Resulting binary
should work from SRAM, DDR2 and SPI flash. If started from DDR2 RAM
level initialization will skipped.
