1.About the document
  I am a newbie to linux kernel! But maybe some people need this,so ...

2.What did I do to "get places on the E2" ?
  The biggest difficulty is howto debug the kernel before it can print messeges on the screen or to UART.The MBM module has initiate the LCD,so I tried to get the start address of LCD framebuffer and then I can put strings onto LCD.(the address is got via a program that read some LCD controller registers,the address is:0xa0080000,that's why we will see random pixels when we boot kernel via boot_usb)
  Now we can track the kernel code step by step,by adding codes which can display useful information into the kernel.The kernel boot sequence: 

	arch/arm/boot/compressed/head.S:		start
	arch/arm/boot/compressed/head-xscale.S:	*
	arch/arm/boot/compressed/head.S			*
	arch/arm/boot/compressed/misc.c:		decompress_kernel
	arch/arm/boot/compressed/head.S:		call_kernel
	arch/arm/kernel/head.S:					stext
	arch/arm/kernel/head-common.S:			__lookup_processor_type
											__lookup_machine_type
	arch/arm/kernel/head.S:					__create_page_tables
	arch/arm/mm/proc-xscale.S:				__xscale_setup
	arch/arm/kernel/head.S:					__enable_mmu
	arch/arm/kernel/head-common.S:			__mmap_switched
	init/main.c:							start_kernel
	arch/arm/kernel/setup.c:				setup_arch
	kernel/sched.c:							sched_init
	arch/arm/kernel/irq.c:					init_IRQ
	init/main.c:							rest_init
  Then "init" is excuted by rest_init.
  There are some crital codes to make the phone boots,you should read the ezx-core.patch in ezx7 or my  r0 patch(it's very small,but enough to make E2 boots,maybe it's better for you if you want to make your NEW phone booting).

3.Notes on porting the driver
  Understand the driver from moto and get enough hardware information first!
  There are hardware differences between EZX phones,E2 have another UDC:ISP 1583,and use SSP SPI of PXA27x(A780/E680 use bit-bang spi).The spi driver has unneeded uncomplexity,the pxa2xx-spi driver in original 2.6 kernel is much simplier,PCAP has just 32 25-bits register,so it's much better than moto's driver.
