it from the uboot net_init() implementation. The routine uses the standard
U-Boot env vars plus a freebsd-specific variable named "rootpath" (the
corresponding u-boot variable for that would be "bootfile" except that it
refers to ubldr, so a new name was needed to communicate the path to ubldr).
This allows ubldr to load a kernel from nfs without requiring a dhcp or
bootp server to provide the server ip and rootpath parameters.
- Only non-sliced bsdlabel style partitioning is currently supported (but provisions
are made towards GPT support, which should follow soon)
- Enable storage support in loader on ARM
Obtained from: Semihalf
- extend ub_dev_read() and ub_dev_recv() so that the actual len and
all error codes can be passed and processed properly; unify behaviour of
these routines
- introduce syscall general error code (API_ESYSC)
This was introduced as a workaround long time ago for some Alpha firmware
(which is now gone), and actually prevented net_close() to ever be
called.
Certain firmwares (U-Boot) need local shutdown operations to be performed on a
network controller upon transaction end: such platform-specific hooks are
supposed to be called via netif_close() (from within net_close()).
This change effectively reverts the following CVS commit:
sys/boot/common/dev_net.c
revision 1.7
date: 2000/05/13 15:40:46; author: dfr; state: Exp; lines: +2 -1
Only probe network settings on the first open of the network device.
The alpha firmware takes a seriously long time to open the network device
the first time.
Also suppress excessive output while netbooting via loader, unless debugging.
While there, make sys/boot/uboot more style(9) compliant.
