[U-Boot] [PATCH 1/2] test/py: move find_ram_base() into u_boot_utils

Dear Stephen,

On which boards did you test this feature?  Eventually ARM only?

Searching for "-> start" is probably not exactly portable.  For
example, on a PowerPC system the output of "bdi" might look like this:

=> bdi
memstart    = 0x00000000
memsize     = 0x04000000
flashstart  = 0xFC000000
flashsize   = 0x02000000
flashoffset = 0x0005D000
sramstart   = 0x00000000
sramsize    = 0x00000000
bootflags   = 0x00000000
intfreq     =    396 MHz
busfreq     =    132 MHz
ethaddr     = 00:D0:93:2A:C2:1A
IP addr     = 192.168.240.240
baudrate    = 115200 bps
relocaddr   = 0x03F47000
=> 

[example is from a TQM5200S, U-Boot 2016.01-00223-gb57843e]

Best regards,
