+Andes Technology SoC AG102
+==========================
+
+AG102 is the second SoC produced by Andes Technology using N1213 CPU core
+with FPU and DDR contoller support.
+AG102 has integrated both AHB and APB bus and many periphals for application
+and product development.
+
+ADP-AG102
+=========
+
+ADP-AG102 is the SoC with AG102 hardcore CPU.
+
+Configurations
+==============
+
+CONFIG_MEM_REMAP:
+ Doing memory remap is essential for preparing some non-OS or RTOS
+ applications.
+
+CONFIG_SKIP_LOWLEVEL_INIT:
+ If you want to boot this system from SPI ROM and bypass e-bios (the
+ other boot loader on ROM). You should undefine CONFIG_SKIP_LOWLEVEL_INIT
+ in "include/configs/adp-ag102.h".
+
+Build and boot steps
+====================
+
+build:
+1. Prepare the toolchains and make sure the $PATH to toolchains is correct.
+2. Use `make adp-ag102` in u-boot root to build the image.
+
+Burn u-boot to SPI ROM:
+====================
+
+This section will be added later.

First do a dry run:
-$ ./tools/scripts/patman/patman -n
+$ ./tools/patman/patman -n
If it can't detect the upstream branch, try telling it how many patches
there are in your series:
-$ ./tools/scripts/patman/patman -n -c5
+$ ./tools/patman/patman -n -c5
This will create patch files in your current directory and tell you who
it is thinking of sending them to. Take a look at the patch files.
-$ ./tools/scripts/patman/patman -n -c5 -s1
+$ ./tools/patman/patman -n -c5 -s1
Similar to the above, but skip the first commit and take the next 5. This
is useful if your top commit is for setting up testing.
Where Patches Are Sent
======================
-Once the patches are created, patman sends them using gti send-email. The
+Once the patches are created, patman sends them using git send-email. The
whole series is sent to the recipients in Series-to: and Series-cc.
You can Cc individual patches to other people with the Cc: tag. Tags in the
subject are also picked up to Cc patches. For example, a commit like this:
