Add these two tables which are supported by ACPICA tools so mab understands
these tables also.

Since 3.13 kernel birngs a lot of new features and APEI structure refines,
we need to update our tool to make it works with APEI blob.

We create blob with memory error example as a proof it really works.
This commits only add more detailed info so output message will

bfapei now can create blob for EINJ driver as well.
Blob for EINJ driver need to be combined with blob for HEST driver since
EINJ is designed to set status flag for Error Status Block pointed from
HEST table. This way EINJ driver can be tested in easy way. Note that
SCI must be triggered in the next step so GHES driver start to parse error.
This could be done using SCI emulate mechanism.
Logic path:
1. Create Error Status Block (ESB information related to given error,
pointed by HEST)
2. Create pretended registers (blob for EINJ) that instruct kernel to
set status flag in ESB.
3. Trigger error using debugfs
4. Emulate SCI
HOWTO:
Enter to acpi tool repository:
# make PADDR=0x<physical address> APEI=einj <platform>.acpi
Boot target:
Print available error list:
# cat /sys/kernel/debug/apei/einj/available_error_type
0x00000008 Memory Correctable
Set given error type:
# echo 0x00000008 > /sys/kernel/debug/apei/einj/error_type
Confirm error was really set:
# cat /sys/kernel/debug/apei/einj/error_type
0x8
Inject error (here status flag for ESB is set)
# echo 0x00000008 > /sys/kernel/debug/apei/einj/error_inject
Emulate SCI (notification of HED device with 0x80 value)
# echo "HED 128" > /sys/kernel/debug/acpi/sci_notify
ACPI: ACPI device name is <HED>, event code is <128>
ACPI: Notify event is queued

Similar to mab and cab, bfapei "Blob For APEI" create blob which
can be passed to the kernel by special u-boot commands for debugging
purposes. It enable testing of APEI without any h/w interaction.
The idea is to set physical region aside so kernel could reference to it.
Once blob is filling with appropriate value we can pretend registers,
storage etc.
Currently bfapei is able to create blob to test tables like:
o HEST - kernel need to trigger error, related error info is ready to read
root@localhost:~# echo 1 > /sys/kernel/debug/apei/einj/error_inject
{1}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 2
{1}[Hardware Error]: APEI generic hardware error status
{1}[Hardware Error]: severity: 1, fatal
{1}[Hardware Error]: section: 0, severity: 0, recoverable
{1}[Hardware Error]: flags: 0x00
{1}[Hardware Error]: section_type: memory error
o BERT - kernel check list of errors (boot process) pointed from BERT,
any errors with status flag set is printed out
[...]
[Hardware Error]: Error record from previous boot:
{1}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 2
{1}[Hardware Error]: APEI generic hardware error status
{1}[Hardware Error]: severity: 1, fatal
{1}[Hardware Error]: section: 0, severity: 0, recoverable
{1}[Hardware Error]: flags: 0x00
{1}[Hardware Error]: section_type: memory error
[...]
O ERST - appropriate registers are set so when there is kernel panic
ERST driver dump log to region reserved within the blob,
once kernel back to life it can mount pstore file system and
read logs (files) for more details
panic!
[...]
root@localhost:~# mount -t pstore - /sys/fs/pstore
root@localhost:~# ll /sys/fs/pstore/
total 0
drwxr-xr-x 2 root root 0 Sep 5 15:19 ./
drwxr-xr-x 4 root root 0 Jan 1 1970 ../
-r--r--r-- 1 root root 29374 Sep 5 14:01 dmesg-erst-0
HOWTO:
Add appropriate flag to make command:
make PADDR=0x42010000 APEI=<einj|bert|erst> exynos5250-arndale.acpi

While trying to hunt down what appeared to be structural errors in
an ACPI blob, I got tired of double checking pointers and load addresses
by hand (and having to double check my lousy arithmetic). So, cab
will search a blob for tables using brute force to determine where
tables actually are, and then compare those locations with where all
the table pointers say they should be, reporting any discrepancies
found. Cab will also double check all table headers looking for
invalid checksums, and table revision levels older than current
ACPI 5.0 spec dictates.
If you can think of additional checks on tables, please add them.

When doing relocation cleanup in the FADT, we need to use
_either_ the 32- or 64-bit addresses, and not both (which
is what we currently do); add a -f option to tell mab to use
32-bit in the FADT, and default to 64-bit otherwise. NB: 64-bit
is always the safe choice but 32-bit needs to be allowed for those
that use it to ensure they use addresses < 4GB for loadable tables.

Add a new argument -p <paddr> which takes the physical address of the
final location of the blob in physical memory.
If this is supplied mab will then fixup the addresses in the tables to
point to correct physical locations and further fixups in the kernel are
no longer needed.
This produces table blobs that are more like what we can expect from
firmware.
