David Bauer 4cd5ce5a7f ramips: increase SPI frequency for MT7620 Archer 
Increase the SPI frequency for the MT7620 based TP-Link Archer
series to 30MHz.

TP-Link uses different SPI flash chips for the same board
revision, so be conservative to not break boards with a
different chip. 30MHz should be well supported by all chips.

Tested on Archer C2 v1 (GD25Q64B) and Archer C20i (W25Q64FV).

Archer C20i (before)
====================
root@OpenWrt:~# time dd if=/dev/mtd1 of=/tmp/test.bin bs=64k
122+0 records in
122+0 records out
real	0m 15.30s
user	0m 0.00s
sys	0m 15.29s

Archer C20i (after)
===================
root@OpenWrt:~# time dd if=/dev/mtd1 of=/tmp/test.bin bs=64k
122+0 records in
122+0 records out
real	0m 5.99s
user	0m 0.00s
sys	0m 5.98s

 -----------------------------------------------------

This is the buildsystem for the OpenWrt Linux distribution.

To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.

You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.

1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default

2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/

3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.

4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
