I am trying to use an Atheros AR6103 wifi module (SDIO interface) on the Zedboard.
As it is said on the Xilinx wiki website, the driver for the AR6103 is already part of the linux kernel,
here it is: http://www.wiki.xilinx.com/Zynq+SDIO+WiFi and http://wireless.kernel.org/en/users/Drivers/ath6kl.
The problem is that the wifi module comes in the forms of a SD card shape, but I have to use the SD slot on the Zedboard to boot the linux kernel. If I use a Pmod to SD module to extend with one SD slot, I have also to configure another SDIO controller in the PS using EMIOs to connect the Pmod.
What changes should I do if I want to use this integrated driver software in the Linux kernel ? I know I have to regenerate the FSBL and bitstream. What about the u-boot ? or any changes when building the linux kernel ? Does the driver software automatically works with two SDIO controller ?
