Some issue about CA816x/819x EVM board

Hi,

I got one CA816x/819x EVM board, the board can be boot thru image which is compiled from arago git(http://arago-project.org/git/projects/?p=linux-omap3.git;a=summary, and I used the tag 2.6.34_TI816XPSP_04.00.00.07),
I found some issues about the board, these issues are existed in both arago image and the demo image.

1. SD/MMC card slot hot-plug issue
SD/MMC card slot can't support hot-plug, the SD card can only be identify if it was pluged into slot before
system boot. After check the code of arago git, it seems the gpio part wasn't enabled since I found the
gpio_bank_count is zero in arch/arm/plat-omap/gpio.c, I want to add gpio bank support in the file, however
I can't find gpio base address in AM389x Sitara ARM Microprocessors (MPUs) Technical Reference Manual.

2. SATA interface issue
SATA disk only works well if connect with SATA0/J12, the disk can't be recognize if connect with SATA1/J11.

Does anyone has some hints for these? Thanks in advance!

Best Regards,
Xiao Jiang
