Only erase the first 4KB of the partition and set to 0. fs_mgr will format the partiton if all 0 in first 4kB. 1. Reduce flash time for installer.efi 2. Reduce flash time for fastboot on userdebug build Tracked-On: OAM-103807 Signed-off-by: Chen, Gang G <gang.g.chen@intel.com>
If you use PC to burn the ISO image to USB stick, and forget to plug out the USB stick from PC, then reboot your PC with USB stick plugged. Celadon ISO image will be installed to the PC automatically without notification. Thus it will damage the data in your PC. So we add UI to ask the user to confirm if continue or stop flashing celadon images to this device to avoid data damage. Tracked-On: OAM-103809 Signed-off-by: Chen, Gang G <gang.g.chen@intel.com>

SBL UEFI payload is only able to boot EFI app and OSloader payload only support ELF image. In SBL, we only build kernelflinger as ELF image. If includes both kf4sbl.elf and kernelflinger.efi to bootloader.img, android can always boot whether uses SBL UEFI payload or Osloader payload. If will convenient for developer and validation.

UEFI provides TPM boot time services for kernerlflinger. But SBL doesn't provide such services. So TPM driver is required to communicate to TPM hardware module for SBL. TPM driver is ported from SBL firmware which is BSD-2 license. Tracked-On: OAM-110881 Signed-off-by: Chen, Gang G <gang.g.chen@intel.com>

If the bootloader partition is NON EFI System partition, perform "safe flash procedure" is not required. Because for NON-EFI, it can't leverage UEFI runtime service to verify new flashed image Tracked-On: OAM-111722 Signed-off-by: Chen, Gang G <gang.g.chen@intel.com>

1. share_data partition is very large, it'd better support fast erase for share_data partition in userdebug build. 2. Currently slot_label return NULL if there is no active slot, return the first suffix instead. Tracked-On: OAM-112930 Signed-off-by: jizhenlo <zhenlong.z.ji@intel.com>

Currently kernelflinger assumes the boot device is always behind a PCI bridge. But the device might be directly on the root complex, like the passthrough device or emulated device in ACRN, such assumption causes boot failure. Fix it by using the BDF directly when boot device is on bus 0. Tracked-On: OAM-113030 Signed-off-by: Jiaqing Zhao <jiaqing.zhao@intel.com>
installer and fastboot may use installer.cmd file simultaneously. For format command, fastboot support creating file system by using 'format:fs_type', such as 'format:f2fs'. But installer doesn't support this syntax, since it only supports 2 arguments for format command currently. Add support for format type syntax in installer so file system can be formatted based on the fs_type provided. Tracked-On: OAM-113370 Signed-off-by: jizhenlo <zhenlong.z.ji@intel.com>

Some device uses a different "booting from two block devices" design, requiring kernelflinger to pass the 2nd boot device to Android by androidboot.boot_devices. Add "secondary_diskbus" option for setting that value, the format is the same as "diskbus". This feature is controlled by "TARGET_HAS_2ND_BOOTDEV" compile flag.
