HimalayaSerial

You need this patch to enable support for Serial Cable during boot. (Useful during bootloader debugging, not necessary otherwise)

You need to enable : CONFIG_DEBUG_LL, __CONFIG_DEBUG_PXA_BTUART__ in configuration. (make menuconfig)

Based on descriptions found in the registry, the following ports and locations are found (HTC_Serial):

name	Port	wince name	type	wince virtual address
/dev/ttyS1	BTUART	COM1:	Serial cable	0xae200000
/dev/ttyS2	STUART	COM2:	GSM command	0xae700000
/dev/ttyS0	FFUART	COM9:	GSM Data	0xae100000
