Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips.
I have "ported" U-boot to a in house made board with Numonyx Axcell P33/P30
256-Mbit 65nm flash chips.
After some time :( searching for bugs in our board or soft, we have
discovered that those chips have a small but annoying bug, documented in
"Numonyx Axcell P33/P30 256-Mbit Specification Update"
It states :
When customer uses [...] block unlock, the block lock status might be
altered inadvertently. Lock status might be set to either 01h or 03h
unexpectedly (00h as expected data), which leads to program/erase failure
on certain blocks.
A working workaround is given, which I have applied and tested with success :
Workaround: If the interval between 60h and its subsequent command
can be guaranteed within 20us, Option I is recommended,
otherwise Option II (involves hardware) should be selected.
Option I: The table below lists the detail command sequences:
Command
Data bus Address bus Remarks
Sequence
1 90h Block Address
Read Lock Status
2 Read Block Address + 02h
(2)(3) (1)
3 60h Block Address
(2)(3) (1) Lock/Unlock/RCR Configuration
4 D0h/01h/03h Block Address
Notes:
(1) Block Address refers to RCR configuration data only when the 60h
command sequence is used to set RCR register combined with 03h
subsequent command.
(2) For the third and fourth command sequences, the Block Address must
be the same.
(3) The interval between 60h command and its subsequent D0h/01h/2Fh/03h
commands should be less than 20us.
And here is a log comparison of a simple (destructive) flash test without
and with the workaround.

sector_erased().
- Because of this, we don't have variable declarations inside the

env_nand: return error when no device is found
Currently, if there is an error probing the NAND chip and the env is based
in NAND, the readenv() function will use a NULL function pointer and thus
jump to address 0.
Here I just check for a non-zero value of blocksize as that shouldn't be
zero when a valid device is found, but perhaps there is a better way for
someone familiar with the NAND internals to suggest.

fdt: Fix bug in size calculation in fdt_resize() with initrd use
Original bug description from Feng (fdt_resize() bug caused "WARNING:
could not set linux, initrd-start FDT_ERR_NOSPACE."):
What I got is an error: "WARNING: could not set linux,initrd-start
FDT_ERR_NOSPACE." after loading Device Tree blob. This in turn caused
linux to miss init part.
After some digging, I found out the reason for this error, it is caused
by fdt_resize().
FDT blob got resized after filling in all board specific information of
PowerPC. (in boot_body_linux()). It reduced blob size with only extra
space for two fdt_reserve_entry, one for fdt itself, and one for initrd.
Then it's aligned to a 0x1000 page boundary. However, later in
fdt_initrd(), it could add two more properties, initrd-start AND
initrd-end, each one needs at least two fdt_reserve_entry sizes done by
_fdt_add_property() (name and value). Thus, the two fdt_reserve_entry
extra space is not sufficient.
So for some specific fdt size which is just under the page boundary
after resizing, this will cause an error of FDT_ERR_NOSPACE in
fdt_initrd() when setting those two properties, and failed to pass
initrd information to linux.
My fix is in fdt_resize(), leave at least 4 fdt_reserve_entry for
initrd. So instead of 2*sizeof(struct fdt_reserve_entry) for
actual_totalsize, use 5*sizeof(struc fdt_reserve_entry).
Stefan: I got this same error on katmai, when trying to boot with
initrd (run flash_self). This patch fixes this issue.

fdt relocate: have more attention to use a bootmap or not
Platforms with flat device tree support can use a bootmap to relocate
the fdt_blob. This is not a must. That's why the relocation function
boot_relocate_fdt() should be use only if CONFIG_OF_LIBFDT was defined
together with CONFIG_SYS_BOOTMAPSZ (see common/cmd_bootm.c).
On MicroBlaze platforms there is no need to use a bootmap to relocate
a fdt blob. So we need a more precise focus on the compilation and usage
of boot_relocate_fdt().
In general it is valid to exclude the function boot_relocate_fdt() if
the bootmap size CONFIG_SYS_BOOTMAPSZ is not defined.

Rename getenv_r() into getenv_f()
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.).

generally means "running from RAM", i. e. _after_ relocation.
