This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.
Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]
Mark known build failures as NO_PIE for now.
The only known runtime failure was rtld.

(7-bit device address << 1), always leaving the room for the read/write bit.
This commit convert ti_i2c and revert r259127 on bcm2835_bsc to make them
compatible with 8-bit addresses. Previous to this commit an i2c device
would have different addresses depending on the controller it was attached
to (by example, when compared to any iicbb(4) based i2c controller), which
was a pretty annoying behavior.
Also, update the PMIC i2c address on beaglebone* DTS files to match the new
address scheme.
Now the userland utilities need to do the correct slave address shifting
(but it is going to work with any i2c controller on the system).

loader_brand="mycustom-brand"
Then "mycustom-brand" will be executed instead of "fbsd-logo".

having a similar construct that's related to the CWARNFLAGS changes.
lindev(4) was only used to provide /dev/full which is now a standard feature of
FreeBSD. /dev/full was never linux-specific and provides a generally useful
feature.
Document this in UPDATING and bump __FreeBSD_version. This will be documented
in the PH shortly.

copy of the code from boot1.chrp again.
The resulting image is installed to /boot/boot1.efifat. If dd'ed to an 800K
"efi" partition, it should result in a bootable system.
NetFPGA-10G Embedded CPU Ethernet Core.
The current version operates on a simple PIO based interface connected
to a NetFPGA-10G port.
To avoid confusion: this driver operates on a CPU running on the FPGA,
e.g. BERI/mips, and is not suited for the PCI host interface.

uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.
the PowerPC port with all the Open Firmware bits removed and replaced by
their EFI counterparts. On the whole, I think I prefer Open Firmware.
This code is supposed to be an immutable shim that sits on the EFI system
partition, loads /boot/loader.efi from UFS and tells the real loader what
disk/partition to look at. It finds the UFS root partition by the somewhat
braindead approach of picking the first UFS partition it can find. Better
approaches are called for, but this works for now. This shim loader will
also be useful for secure boot in the future, which will require some
rearchitecture.
Previously ${COMPILER_TYPE} was checked in sys/boot/amd64, and the efi
subdirectory was skipped altogether for gcc (since GCC does not support
a required attribute). However, during the early buildworld stages
${COMPILER_TYPE} is the existing system compiler (i.e., gcc on 9.x build
hosts), not the compiler that will eventually be used. This caused
"make obj" to skip the efi subdirectory. In later build stages
${COMPILER_TYPE} is "clang", and then the efi loader would attempt to
build in the source directory.
