+Andes Technology SoC AG101P
+===========================
+
+AG101P is the mainline SoC produced by Andes Technology using N1213 CPU core
+with FPU and DDR contoller support.
+AG101P has integrated both AHB and APB bus and many periphals for application
+and product development.
+
+ADP-AG101P
+=========
+
+ADP-AG101P is the SoC with AG101 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-ag101p.h".
+
+Build and boot steps
+====================
+
+build:
+1. Prepare the toolchains and make sure the $PATH to toolchains is correct.
+2. Use `make adp-ag101p_defconfig` in u-boot root to build the image.
+
+Burn u-boot to SPI ROM:
+====================
+
+This section will be added later.

-Andes Technology SoC AG101
-==========================
-
-AG101 is the first SoC produced by Andes Technology using N1213 CPU core.
-AG101 has integrated both AHB and APB bus and many periphals for application
-and product development.
-
-ADP-AG101
-=========
-
-ADP-AG101 is the SoC with AG101 hardcore CPU.
-
-Please check http://www.andestech.com/p2-4.htm for detail of this SoC.
-
-Configurations
-==============
-
-CONFIG_MEM_REMAP:
- Doing memory remap is essential for preparing some non-OS or RTOS
- applications.
-
- This is also a must on ADP-AG101 board.
- (While other boards may not have this problem).
-
- The reason is because the ROM/FLASH circuit on PCB board.
- AG101-A0 board has 2 jumpers MA17 and SW5 to configure which
- ROM/FLASH is used to boot.
-
- When SW5 = "0101", MA17 = LO, the ROM is connected to BANK0,
- and the FLASH is connected to BANK1.
- When SW5 = "1010", MA17 = HI, the ROM is disabled (still at BANK0),
- and the FLASH is connected to BANK0.
- It will occur problem when doing flash probing if the flash is at
- BANK0 (0x00000000) while memory remapping was skipped.
-
- Other board like ADP-AG101P may not enable this since there is only
- a FLASH connected to bank0.
-
-CONFIG_SKIP_LOWLEVEL_INIT:
- If you want to boot this system from FLASH and bypass e-bios (the
- other boot loader on ROM). You should undefine CONFIG_SKIP_LOWLEVEL_INIT
- in "include/configs/adp-ag101.h".
-
-Build and boot steps
-====================
-
-build:
-1. Prepare the toolchains and make sure the $PATH to toolchains is correct.
-2. Use `make adp-ag101` in u-boot root to build the image.
-
-burn u-boot to flash:
-1. Make sure the MA17 (J16) is Lo.
-2. Make sure the dip switch SW5 is set to "0101".
-3. Power On. Press button "S1", then press button "SW1", then you will found the
- debug LED show 67 means the system successfully booted into e-bios.
- Now you can control the e-bios boot loader from your console.
-4. Under "Command>>" prompt, enter "97" (CopyImageFromCard)
-5. Under "Type Dir Name of [CF/SD] =>" promtp, enter "c".
-6. Under "Enter Filename =>" prompt, enter the file name of u-boot image you
- just build. It is usually "u-boot.bin".
-7. Under "Enter Dest. Address =>" prompt, enter the memory address where you
- want to put the binary from SD card to RAM.
- Address "0x500000" is our suggestion.
-8. Under "Command>>" prompt again, enter "55" (CLI) to use interactive command
- environment.
-9. Under "CLI>" prompt, enter "burn 0x500000 0x80400000 0x30000" to burn the
- binary from RAM to FLASH.
-10. Under "CLI>" prompt, enter "exit" to finish the burn process.
-
-boot u-boot from flash:
-1. Make sure the MA17 (J16) is Hi).
-2. Make sure the dip switch SW5 is set to "1010".
-3. Power On. Press button "S1", then you will see the debug LED count to 20.
-4. Now you can use u-boot on ADP-AG101 board.

-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.
