FreeBSD/src ff29b85 (r302190) — sys/mips/atheros ar71xx_chip.c ar71xx_machdep.c, sys/mips/broadcom bcm_machdep.c uart_cpu_chipc.c
Replace mips/sentry5 with mips/broadcom
The delta between SENTRY5 and BCM was already small due to BCM being
derived from SENTRY5; re-integrating the two avoids the maintenance
overhead of keeping them both in sync with bhnd(4) changes.
- Re-integrate minor SENTRY5 deltas in bcm_machdep.c
- Modify uart_cpu_chipc to allow specifying UART debug/console flags via
kenv and device hints.
- Switch SENTRY5 to std.broadcom
- Enabled CFI flash support for SENTRY5
