Now that we have consistently named symbols to enable USB host or gadget
controller support in SPL or full U-Boot, we do not need to
unconditionally build USB files nor depend on non-SPL symbols to know
when to build these common files.

As this particular platform is intended to be loaded and run a specific
set of routines in SPL, we do not need the ability to further use the
USB as a host device in SPL. Disable this support.

A crafted squashfs image could embed a huge number of empty metadata
blocks in order to make the amount of malloc()'d memory overflow and be
much smaller than expected. Because of this flaw, any random code
positioned at the right location in the squashfs image could be memcpy'd
from the squashfs structures into U-Boot code location while trying to
access the rearmost blocks, before being executed.
In order to prevent this vulnerability from being exploited in eg. a
secure boot environment, let's add a check over the amount of data
that is going to be allocated. Such a check could look like:
if (!elem_size || n > SIZE_MAX / elem_size)
return NULL;
The right way to do it would be to enhance the calloc() implementation
but this is quite an impacting change for such a small fix. Another
solution would be to add the check before the malloc call in the
squashfs implementation, but this does not look right. So for now, let's
use the kcalloc() compatibility function from Linux, which has this
check.

When running "i2c md 0 0 80000100", the function do_i2c_md parses the
length into an unsigned int variable named length. The value is then
moved to a signed variable:
int nbytes = length;
#define DISP_LINE_LEN 16
int linebytes = (nbytes > DISP_LINE_LEN) ? DISP_LINE_LEN : nbytes;
ret = dm_i2c_read(dev, addr, linebuf, linebytes);
On systems where integers are 32 bits wide, 0x80000100 is a negative
value to "nbytes > DISP_LINE_LEN" is false and linebytes gets assigned
0x80000100 instead of 16.
The consequence is that the function which reads from the i2c device
(dm_i2c_read or i2c_read) is called with a 16-byte stack buffer to fill
but with a size parameter which is too large. In some cases, this could
trigger a crash. But with some i2c drivers, such as drivers/i2c/nx_i2c.c
(used with "nexell,s5pxx18-i2c" bus), the size is actually truncated to
a 16-bit integer. This is because function i2c_transfer expects an
unsigned short length. In such a case, an attacker who can control the
response of an i2c device can overwrite the return address of a function
and execute arbitrary code through Return-Oriented Programming.
Fix this issue by using unsigned integers types in do_i2c_md. While at
it, make also alen unsigned, as signed sizes can cause vulnerabilities
when people forgot to check that they can be negative.

Currently CONFIG_SPL_TEXT_BASE and CONFIG_SYS_TEXT_BASE addresses are
manually increased by 0x1000 due to .bootpg section. This section has size
of 0x1000 bytes and is manually put by linker script before .text section
(and therefore before base address) when CONFIG_SYS_MPC85XX_NO_RESETVEC is
set. Due to this fact lot of other config options are manually increased by
0x1000 value to make correct layout. Note that entry point is not on
CONFIG_SPL_TEXT_BASE (image+0x1000) but it is really on address
CONFIG_SPL_TEXT_BASE-0x1000 (means at the start of the image).
Cleanup handling of .bootpg section when CONFIG_SYS_MPC85XX_NO_RESETVEC is
set. Put .bootpg code directly into .text section and move text base
address to the start of .bootpg code. And finally remove +0x1000 value from
lot of config options. With this removal custom PHDRS is not used anymore,
so remove it too.
After this change entry point would be at CONFIG_SPL_TEXT_BASE and not at
address -0x1000 anymore.

Do DDR initialization using the procedural mx6_dram_cfg() instead of
programming the MMDC using a raw list of register/value pairs, this
solves some rare boot failures on specific "bad" modules.
Calibration values, DDR geometry are unchanged, memory timings are
updated according to the relevant memory datasheet, no changes on
the power consumption.
For IT temperature range SKUs CL is decreased from 8 to 7 and tFAW
value is increased, for commercial temperature range SKUs some
changes on ODT parameters.
This change was validated over a range of different apalis-imx6 SoM, on
the whole working temperature range with weeks of continuous testing.
