tools: fix define2mk.sed to not add quotes around negative integers
The sed script, tools/scripts/define2mk.sed, converts config defines
from C headers into include/autoconf.mk for the use in Makefiles.
I found the tool adds quotes around negative integer values.
For example, at the point of the v2016.07-rc1 tag,
include/configs/microblaze-generic.h defines
#define CONFIG_BOOTDELAY -1 /* -1 disables auto-boot */
Because it is an integer option, it should be converted to:
CONFIG_BOOTDELAY=-1
But, the script actually converts it to:
CONFIG_BOOTDELAY="-1"
This is a fatal problem for the tools/moveconfig.py because it parses
include/autoconf.mk for the config defines from the board headers.
CONFIG_BOOTDELAY="-1" is considered as a string type option and it
is dropped due to the type mismatch from the entry in Kconfig.
This commit fixes the script so that the tools/moveconfig.py can
correctly convert integer options with a negative value.

tools: moveconfig: do not rely on type and default value given by users
Commit 96464badc794 ("moveconfig: Always run savedefconfig on the
moved config") changed the work flow of this tool a lot from the
original intention when this tool was designed first.
Since then, before running this tool, users must edit the Kconfig to
add the menu entries for the configs they are moving. It means users
had already specified the type and the default value for each CONFIG
via its Kconfig entry. Nevertheless, users are still required to
dictate the same type and the default value in the input file. This
is tedious to use. So, my idea here is to deprecate the latter.
Before moving forward with it, there is one issue worth mentioning;
since the savedefconfig re-sync was introduced, this tool has not
been able to move bool options with "default y". Joe sent a patch
to solve this problem about a year ago, but it was not applied for
some reasons. Now, he came back with an updated patch, so this
problem will be fixed soon.
For other use cases, I see no reason to require redundant dictation
in the input file. Instead, the tool can know the types and default
values by parsing the .config file.
This commit changes the tool to use the CONFIG names, but ignore the
types and default values given by the input file.
This commit also fixes one bug. Prior to this commit, it could not
move an integer-typed CONFIG with value 1.
For example, assume we are moving CONFIG_CONS_INDEX. Please note
this is an integer type option.
Many board headers define this CONFIG as 1.
#define CONFIG_CONS_INDEX 1
It will be converted to
CONFIG_CONS_INDEX=y
and moved to include/autoconf.mk, by the tools/scripts/define2mk.sed.
It will cause "make savedefconfig" to fail due to the type conflict.
This commit takes care of it by detecting the type and converting the
CONFIG value correctly.

x86: baytrail: Change fsp, emmc-boot-mode to "auto"
At present all BayTrail boards configure fsp,emmc-boot-mode to 2,
which means "eMMC 4.1" per FSP documentation. However, eMMC 4.1
only shows up on some early stepping silicon of BayTrail SoC.
Newer stepping SoC integrates an eMMC 4.5 controller. Intel FSP
provides a config option fsp,emmc-boot-mode which tells FSP which
eMMC controller it initializes. Instead of hardcoded to 2, now
we change it to 1 which means "auto".
With this change, MinnowMax board (with a D0 stepping BayTrail SoC)
can see the eMMC 4.5 controller at PCI address 00.17.00 via U-Boot
'pci' command.

An accumulated length was incorrectly added to current each pass
through the loop. On system with more than 2 cores this caused a
corrupt MADT to be generated.

armv8: ls2080aqds: Enable QSPI boot support
This patch adds QSPI boot support for LS2080AQDS board.
The QSPI boot image need to be programmed into the QSPI flash
first. Then we can switch to booting from QSPI memory space.
