*	Consolidate the vendor space misc usage for Pixels	Tianjie Xu	2019-11-12	5	-80/+442
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The layout of the vendor space /misc partition was pretty confusing and lead to some usage conflicts. To formalize the layout, we create a pixel specific library with the definition & offset of various flags. The new library also handles the R/W. As a result, we will leave system domain /misc definitions in the libbootloader_message. We also switch the misc_writer binary to use more specific options instead of writing an arbitrary hex string. So we can avoid redefining the string & offset in both init script and recovery ui. Bug: 131775112 Test: unit tests pass, run misc_writer and check contents of /misc Change-Id: I00f8842a81d1929e31a1de4d5eb09575ffad47c0
*	Add misc_writer.	Tao Bao	2019-05-21	2	-0/+146
	bootloader_message.h currently divides /misc into four segments. The space between 2K and 16K is reserved for vendor use (e.g. bootloader persists flags). This CL adds a vendor tool "misc_writer", to allow writing data to the vendor space in /misc, before getting a dedicated HAL for accessing /misc partition (b/131775112). Targets need to explicitly include the module, then invoke the executable to write data. For example, the following command will write 3-byte data ("0xABCDEF") to offset 4 in vendor space (i.e. 2048 + 4 in /misc). $ /vendor/bin/misc_writer --vendor-space-offset 4 --hex-string 0xABCDEF Bug: 132906936 Test: Run recovery_unit_test on crosshatch. Test: Call the command via init.hardware.rc on crosshatch. Check that the call finishes successfully. Then check the contents written to /misc (`dd bs=1 skip=2048 if=/dev/block/sda2 count=32 \| xxd`). Change-Id: I79548fc63fc79b705a0320868690569c3106949f
