+Keymile kmeter1 Board
+-----------------------------------------
+1. Alternative Boot EEPROM
+
+ Upon the kmeter1 startup the I2C_1 controller is used to fetch the boot
+ configuration from a serial EEPROM. During the development and debugging
+ phase it might be helpful to apply an alternative boot configuration in
+ a simple way. Therefore it is an alternative boot eeprom on the PIGGY,
+ which can be activated by setting the "ST" jumper on the PIGGY board.
+
+2. Memory Map
+
+ BaseAddr PortSz Size Device
+ ----------- ------ ----- ------
+ 0x0000_0000 64 bit 256MB DDR
+ 0x8000_0000 8 bit 256KB GPIO/PIGGY on CS1
+ 0xa000_0000 8 bit 256MB PAXE on CS3
+ 0xe000_0000 2MB Int Mem Reg Space
+ 0xf000_0000 16 bit 256MB FLASH on CS0
+
+
+ DDR-SDRAM:
+ The current realization is made with four 16-bits memory devices.
+ Mounting options have been foreseen for device architectures from
+ 4Mx16 to 512Mx16. The kmeter1 is equipped with four 32Mx16 devices
+ thus resulting in a total capacity of 256MBytes.
+
+3. Compilation
+
+ Assuming you're using BASH shell:
+
+ export CROSS_COMPILE=your-cross-compile-prefix
+ cd u-boot
+ make distclean
+ make kmeter1_config
+ make
+

+ Or via tftp:
+
+ tftp 10000 u-boot.bin
+ => run load
