Subject: ramips: introduce TP-Link v1 header OKLI image recipe
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=08eecec3558d9adf351e03b58309e69a77de1a36;p=openwrt%2Fstaging%2Fansuel.git

ramips: introduce TP-Link v1 header OKLI image recipe

It can be used to workaround the booting stuck issue caused by the
u-boot LZMA decompression error.

The new kernel image structure:
+------+------------------+------------------+---------------+-----------------+
| name | tplink-v1 header | OKLI lzma-loader | uImage header | lzma kernel+dtb |
+------+------------------+------------------+---------------+-----------------+
| size |      0x200       |       0xe00      |     0x40      |     dynamic     |
+------+------------------+------------------+---------------+-----------------+
