While running from flash, i. e. before relocation, we have only a
limited C runtime environment without writable data segment. In this
phase, some configurations (for example with environment in EEPROM)
must not use the normal getenv(), but a special function. This
function had been called getenv_r(), with the idea that the "_r"
suffix would mean the same as in the _r_eentrant versions of some of
the C library functions (for example getdate vs. getdate_r, getgrent
vs. getgrent_r, etc.).
Unfortunately this was a misleading name, as in U-Boot the "_r"
generally means "running from RAM", i. e. _after_ relocation.
To avoid confusion, rename into getenv_f() [as "running from flash"]

Serial devices currently have to manually stuff \r after every \n found,
but this is a bit more difficult with the jtag console since we process
everything in chunks of 4 bit. So we have to scan & stuff the whole
string rather than what most serial drivers do which is output on a byte
per byte basis.

While we're in here, add some useful debug points. We need custom debug
statements because we need the output to only go to the serial port. If
we used the standard debug helpers, the output would also go to the stdout
(which would be the jtag console) and make it hard to figure out what is
going where exactly.
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
If the other side isn't listening, we should reset the state to ignore
the whole message and not just the part we missed. This makes it easier
to connect at any time to the jtag console without worrying about the two
sides getting out of sync and thus sending garbage back and forth.

Lots of code use this construct:
cmd_usage(cmdtp);

Change cmd_usage() let it return 1 - then we can replace all these

This patch adds the "ecctest" command to test and simulate ECC errors
(single bit and/or double bit) while running from SDRAM. Currently only
the IBM DDR2 controller is supported (405EX, 440SP(e), 460EX/GT).
This is done by copying and calling functions, modifying the SDRAM
controller operation mode, in internal SRAM/OCM.
For correctable ECC errors (single bit) only the status will be printed
since the DDR2 controller doesn't provide the faulting address:
=> ecctest 1000000 1
Using address 01000000 for 1 bit ECC error injection
ECC: Correctable error
Uncorrectable ECC errors (double bit) will also display the faulting
address:
=> ecctest 1000000 2
Using address 01000000 for 2 bit ECC error injection
ECC: Uncorrectable error at 0x0001000000
To enable this "ecctest" function you need to define CONFIG_CMD_ECCTEST
in the board config header.
Tested on katmai and t3corp.

Use the correct macro instead of the hardcoded 0x4c to clear the ECC
status in the 440/460 DDR(2) error status register after ECC
initialization.
Also the non-440 parts (405EX(r) right now) and the IBM DDR PPC variants
(440GX) use a different registers to clear this error status. Use the
correct ones.
