Porting mt7620a+mt7610e driver to OpenWrt trunk (Linux Kernel 3.14.18) (continued: mt7620a)

In accordance with the content of the previous revision of the file will not be error after the compilation, but burned into the flash after the run, there is a problem, as follows:

Workaround:

Porting 7620

1. Add OS/LINUX/RT_FLASH.C content as:

2. Modify OS/LINUX/RT_PROC.C

Will

struct proc_dir_entry *procregdir

Switch

struct proc_dir_entry *procregdir2860v2

and change all calls to Procregdir in the file to: procregdir2860v2

3. Add in Makefile

Rt2860v2_ap-objs + =. /rt2860v2/os/linux/rt_flash.o

4. Modify Include/chip/rt2880.h
Will:

Switch

" Rt_mmap.h " // Fix

5. Modify Include/iface/rtmp_rbs.h

Will:

#define Rtmp_mac_irq_num    4

Switch

#define Rtmp_mac_irq_num    6

6. Modify Include/video.h

Add to

VOID Videoturbinedynamictune (in Prtmp_adapter pAd);
