Commit "mtd: nand: omap: enable BCH ECC scheme using ELM for generic
platform" (d016dc42ce) changed the way
software ECC is configured, both during boot, and during ecc switch, in a way
that is not backwards compatible with older systems:
Older version of omap_gpmc.c always assigned ecc.size = 0 when configuring
for software ecc, relying on nand_scan_tail() to select a default for ecc.size
(256), while the new version of omap_gpmc.c assigns ecc.size = pagesize,
which is likely to not be 256.
Since 1 bit hamming sw ecc is only meant to be used by legacy devices, revert
to the original behavior.

As per OMAP3530 TRM referenced below [1]
For large-page NAND, ROM code expects following ecc-layout for HAM1 ecc-scheme
- OOB[1] (offset of 1 *byte* from start of OOB) for x8 NAND device
- OOB[2] (offset of 1 *word* from start of OOB) for x16 NAND device
Thus ecc-layout expected by ROM code for HAM1 ecc-scheme is:
*for x8 NAND Device*
+--------+---------+---------+---------+---------+---------+---------+
| xxxx | ECC[A0] | ECC[A1] | ECC[A2] | ECC[B0] | ECC[B1] | ECC[B2] | ...
+--------+---------+---------+---------+---------+---------+---------+
*for x16 NAND Device*
+--------+--------+---------+---------+---------+---------+---------+---------+
| xxxxx | xxxxx | ECC[A0] | ECC[A1] | ECC[A2] | ECC[B0] | ECC[B1] | ECC[B2] |
+--------+--------+---------+---------+---------+---------+---------+---------+
This patch fixes ecc-layout *only* for HAM1, as required by ROM-code
For other ecc-schemes like (BCH8) ecc-layout is same for x8 or x16 devices.

The next version VxWorks adopts device tree (for PowerPC and ARM) as its hardware
description mechanism. For PowerPC, the boot interface conforms to
the ePAPR standard, which is:
void (*kernel_entry)(ulong fdt_addr,
ulong r4 /* 0 */,
ulong r5 /* 0 */,
ulong r6 /* EPAPR_MAGIC */, ulong r7 /* IMA size */,
ulong r8 /* 0 */, ulong r9 /* 0 */)
For ARM, the boot interface is:
void (*kernel_entry)(void *fdt_addr)

If U-Boot build with DEBUG enabled/defined the first call of "debug"
function (that dumps data to any available console) will happen before
zeroing of initial "gd" in init call "zero_global_data" in
"init_sequence_f".
And if stack was not filled with zeros chances are high that
"gd->have_console" won't be 0. In its turn it will cause attempt to
output things to non-initialized yet serial console.
So for safety and predictability we set "gd->have_console = 0".

Commit 8dfafdde88 ("Introduce common timer functions") created a
common definition of usec_to_tick() which had a couple problems:
static unsigned long long usec_to_tick(unsigned long usec)
{
uint64_t tick = usec * get_tbclk();
That likely overflows.
usec *= get_tbclk();
That was an attempt to fix it by performing the multiply after the
promotion of usec to 64-bit, but was applied to the wrong variable,
which was never used.
This patch fixes these issues. A user-visible symptom of the problem was
the e.g. "dhcp zImage" using an ASIX USB Ethernet dongle would print:
Waiting for Ethernet connection... unable to connect.
... with no delay before "unable to connect". There are likely other
symptoms.

Some editors such as Emacs can highlight source files.
But their parser algorithm is not perfect.
If you use one double-quotation alone, some editor cannot
handle it nicely and mark source lines as a string by mistake.
It is preferable to use two double-quotations as a pair.

Given a multi-file image created through the mkimage's -d option:
$ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \
multi.img
Image Name: x86
Created: Thu Jul 25 10:29:13 2013
Image Type: Intel x86 Linux Multi-File Image (gzip compressed)
Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB
Load Address: 00000000
Entry Point: 00000000
Contents:
Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB
It is possible to perform the innverse operation -- extracting any file from
the image -- by using the dumpimage's -i option:
$ dumpimage -i multi.img -p 2 System.map
Although it's feasible to retrieve "data files" from image through scripting,
the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
is cumbersome and unreliable -- once you must keep track of file sizes inside
the image. Furthermore, extracting data files using "dumpimage" tool is faster
than through scripting.

In order to avoid duplicating code and keep only one point of modification,
the functions, structs and defines useful for "dumpimage" were moved from
"mkimage" to a common module called "imagetool".
This modification also weakens the coupling between image types (FIT, IMX, MXS,
and so on) and image tools (mkimage and dumpimage). Any tool may initialize the
"imagetool" through register_image_tool() function, while the image types
register themselves within an image tool using the register_image_type()
function:
+---------------+
+------| fit_image |
+--------------+ +-----------+ | +---------------+
| mkimage |--------> | | <-----+
+--------------+ | | +---------------+
| imagetool | <------------| imximage |
+--------------+ | | +---------------+
| dumpimage |--------> | | <-----+
+--------------+ +-----------+ | +---------------+
+------| default_image |
+---------------+
register_image_tool() register_image_type()
Also, the struct "mkimage_params" was renamed to "image_tool_params" to make
clear its general purpose.
