This fixes commit 1a37889b0a:
----------------------->8--------------------
eeprom: Pull out the RW loop
Unify the code for doing read/write into single function, since the
code for both the read and write is almost identical. This again
trims down the code duplication.
----------------------->8--------------------
where the same one routine is utilized for both EEPROM writing and
reading. The only difference was supposed to be a "read" flag which
in both cases was set with 1 somehow.
That lead to a missing delay in case of writing which lead to write
failure (in my case no data was written).

sec_clrbits32() and sec_setbits32() are used which work as

So these must be used with SEC register address as argument.
If the value is read in a local variable, then the functions

DDR has been set as secure in MMU tables. Non-secure master such
as SDHC DMA cannot access data correctly. Mixing secure and non-
secure MMU entries requirs the MMU tables themselves in secure
memory. This patch moves MMU tables into a secure DDR area.
Early MMU tables are changed to set DDR as non-secure. A new
table is added into final MMU tables so secure memory can have
2MB granuality.
gd->secure_ram tracks the location of this secure memory. For
ARMv8 SoCs, the RAM base is not zero and RAM is divided into several
banks. gd->secure_ram needs to be maintained before using. This
maintenance is board-specific, depending on the SoC and memory
bank of the secure memory falls into.

Secure memory is at the end of memory, separated and reserved
from OS, tracked by gd->secure_ram. Secure memory can host
MMU tables, security monitor, etc. This is different from PRAM
used to reserve private memory. PRAM offers memory at the top
of u-boot memory, not necessarily the real end of memory for
systems with very large DDR. Using the end of memory simplifies
MMU setup and avoid memory fragmentation.
"bdinfo" command shows gd->secure_ram value if this memory is
marked as secured.

This patch fixes the DDR3 initialization procedure in
order to comply with DDR3 standard. A 500 us delay is specified
between the DDR3 reset and clock enable signal. Until now,
this delay was not respected. Some DDR3 chips don't bother
but the bigger the RAM becomes the more likely it seems that
this delay is needed. We observed that DRAM > 256 MB from
the manufacturer Samsung have an issue when the specification
is not respected.
Changes:
1) Add a 1 ms wait for L3 timeout error trigger
2) Don't delay DDR3 initialization
Bit 31 of emif_sdram_ref_ctrl shouldn't be set because his
