This patch enforces a rule to always use ACPI_VALIDATE_RSDP_SIG for RSDP
signatures passed from table header or ACPI_SIG_RSDP so that truncated
string comparison can be avoided. This could help to fix the issue that
"RSD " matches but "RSD PTR " doesn't match. Lv Zheng.

This patch fixes an issue that the while loop is not needed as fread()
should return exact the bytes of expected.
The patch is tested by runing diff against the output of "-c" mode and
the normal mode, and only finds the following differences:
1. table addresses: the "-c" mode will always fill 0x0000000000000000 for
the address.
2. RSDP/RSDT/XSDT: there is no generation of such tables for "-c" mode.
So the test result shows the fix is valid. Lv Zheng.

This userspace tool accesses the EC through the ec_sys debug driver
(through /sys/kernel/debug/ec/ec0/io).
The EC command/data registers cannot be accessed directly, because they
may be manipulated by the AML interpreter in parallel.
The ec_sys driver synchronizes user space (debug) access with the AML
interpreter.

This patch updates tools Makefile to use new acpidump.
ACPICA's acpidump relies on various ACPICA components/common/os_specific
source code. They are located in various kernel folders, being searched
and compiled using vpath technique in Makefile. These files include:
1. drivers/acpi/acpica/acapps.h
2. tools/power/acpi/common/getopt.c
3. tools/power/acpi/common/cmfsize.c
4. tools/power/acpi/os_specific/service_layers/oslinuxtbl.c
5. tools/power/acpi/os_specific/service_layers/osunixdir.c
6. tools/power/acpi/os_specific/service_layers/osunixmap.c
This patch has been tested on DELL Inspiron Mini, acpidump output can be
successfully generated by typing the following commands:
# cd tools/power/acpi
# make DEBUG=false
# sudo make install DESTDIR=/opt
# sudo make uninstall DESTDIR=/opt
# make clean
Or
# cd tools
# make acpi
# sudo make acpi_install
# sudo make acpi_uninstall
# make acpi_clean
A kernel build test is also performed on DELL Inspiron Mini to verify that
the changes done to actypes.h and aclinux.h won't affect the kernel
build process.

The acpidump is initiated by Bob Moore and Chao Guan, fixed and completed
by Lv Zheng.
This patch is a generation of the commit that adds acpidump release
automation into ACPICA release process. Lv Zheng.
Note that this patch doesn't replace the kernel shipped acpidump with the
new acpidump. The replacement is done by further patches.

This patch cleans up old tools/power/acpi Makefile for further porting,
make it compiled in a similar way as the other tools. No functional
changes.
The CFLAGS is modified as follows:
1. Previous cc flags:
-Wall -Wstrict-prototypes -Wdeclaration-after-statement -Os -s \
-D_LINUX -DDEFINE_ALTERNATE_TYPES -I../../../include
2. Current cc flags:
DEBUG=false:
-D_LINUX -DDEFINE_ALTERNATE_TYPES -I../../../include -Wall \
-Wstrict-prototypes -Wdeclaration-after-statement -Os \
-fomit-frame-pointer
Normal:
-D_LINUX -DDEFINE_ALTERNATE_TYPES -I../../../include -Wall \
-Wstrict-prototypes -Wdeclaration-after-statement -O1 -g -DDEBUG
There is only one difference: -fomit-frame-pointer.
