This port adds support for:
        1) Serial
        2) eMMC
        3) USB

It has been tested with ARM TRUSTED FIRMWARE running u-boot as the
BL33 executable [see board's README]

eMMC has been tested for reading and booting the loader[1] and linux
kernels as well as saving the u-boot environment.

USB has been tested with ASIX networking adapter and SanDisk 7.4GB
drive.

PSCI has been tested via the reset call.

The firwmare upgrade process has been tested via TFTP and USB FAT
filesystem containing the fastboot.bin image in one of the partitions.

Shouldn't this be 0x780 (i.e. a blknum rather than bytes)

Possibly express these are (0x780 * 512) to make absolutely explicit the 
relationship to the blknum/nblks values?

These are private repositories, no one else can clone from them.  Please
push this somewhere public.

Please use get_ram_size(...) here.  Thanks!

+=================
+
+  > cd ~/poplar/src/l-loader
+  > make clean
+  > make CROSS_COMPILE=arm-linux-gnueabi-
+
+   Due to BootROM requiremets, rename l-loader.bin to fastboot.bin:

+
+
+================================================================================
+			FLASH INSTRUCTIONS
+================================================================================
+
+Two methods:
+
+Using USB debrick support:
+	Copy fastboot.bin to a FAT partition on the USB drive and reboot the
+       poplar board while pressing S3(usb_boot).
+
+       The system will execute the new u-boot and boot into a shell which you
+       can then use to write to eMMC.
+
+Using U-BOOT from shell:
+	1) using AXIS usb ethernet dongle and tftp
+	2) using FAT formated USB drive
+
+
+1. TFTP (USB ethernet dongle)
+=============================
+
+Plug a USB AXIS ethernet dongle on any of the USB2 ports on the Poplar board.
+Copy fastboot.bin to your tftp server.
+In u-boot make sure your network is properly setup.
+
+Then
+
+=> tftp 0x30000000 fastboot.bin

+
+
+2. USING USB FAT DRIVE
+=======================
+
+Copy fastboot.bin to any partition on a FAT32 formated usb flash drive.
+Enter the uboot prompt
+
+=> fatls usb 0:2
