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,

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.

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

On FAT32, instead of fetching the cluster numbers from the FAT, the
code assumed (incorrectly) that the clusters for the root directory
were allocated contiguously. In the result, only the first cluster
could be accessed. At the typical cluster size of 8 sectors this
caused all accesses to files after the first 128 entries to fail -
"fatls" would terminate after 128 files (usually displaying a bogus
file name, occasionally even crashing the system), and "fatload"
would fail to find any files that were not in the first directory
cluster.

The device type was left uninitialized which caused later tests
against DEV_TYPE_UNKNOWN to fail. In the result, "usb part" would
attempt to print information about non-existent devices like this:

Partition Start Sector Num Sectors Type
1 0 2031616 f8
print_part of 1
## Unknown partition table
print_part of 2
## Unknown partition table
print_part of 3
## Unknown partition table
print_part of 4
## Unknown partition table
=>
By initializing the type as DEV_TYPE_UNKNOWN we avoid all the
"Unknown partition table" messages.

will be removed in another patch.]

Lots of code use this construct:

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.
