Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.
If the entry is not found in the env ".flags", then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

!!! fix callback command
When printing all variables with env print, don't print variables that
begin with '.'. If env print is called with a '-a' switch, then
include variables that begin with '.' (just like the ls command).
Variables printed explicitly will be printed even without the -a.

Move the read of the old value to inside the check function. In some
cases it can be avoided all together and at the least the code is only
called from one place.
Also name the function and the callback to more clearly describe what
it does.
Pass the ENTRY instead of just the name for direct access to the whole
data structure.
Pass an enum to the callback that specifies the operation being approved.

Use a flag in hsearch_r for insert mode passed from import to allow the

Now that "do_check" is called for all imports, ensure console init is

capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use
existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network

So add a new field to struct hsearch_data:

when NULL, no check is performed.
And a new argument to himport_r():
o "do_apply": whether to call the apply callback function

The logic of checking special parameters (e.g. baudrate, stdin, stdout,

env_check_apply() which can be called whenever changes are made

When boot from SRIO, slave's ENV can be stored in master's memory space,
then slave can fetch the ENV through SRIO interface.
NOTE: Because the slave can not erase, write master's NOR flash by SRIO
interface, so it can not modify the ENV parameters stored in
master's NOR flash using "saveenv" or other commands.
Master needs to:
1. Put the slave's ENV into it's own memory space.
2. Set an inbound SRIO window covered slave's ENV stored in master's
memory space.
Slave needs to:
1. Set a specific TLB entry in order to fetch ucode and ENV from master.

the calls might have failed. Change this into:
env_buf [32 bytes] too small for value of "hwconfig"
so we know at least which variable caused the overflow; this usually
allows to quickly find the related code as well.

u-boot environments, esp. when boards are shared across multiple
users, can get pretty large and time consuming to visually parse.
The grepenv command this patch adds can be used in lieu of printenv
to facilitate searching. grepenv works like printenv but limits
its output only to environment strings (variable name and value
pairs) that match the user specified substring.
the following examples are on a board with a 5313 byte environment
that spans multiple screen pages:
Example 1: summarize ethernet configuration:
=> grepenv eth TSEC
etact=FM1@DTSEC2
eth=FM1@DTSEC4
ethact=FM1@DTSEC2
eth1addr=00:E0:0C:00:8b:01
eth2addr=00:E0:0C:00:8b:02
eth3addr=00:E0:0C:00:8b:03
eth4addr=00:E0:0C:00:8b:04
eth5addr=00:E0:0C:00:8b:05
eth6addr=00:E0:0C:00:8b:06
eth7addr=00:E0:0C:00:8b:07
eth8addr=00:E0:0C:00:8b:08
eth9addr=00:E0:0C:00:8b:09
ethaddr=00:E0:0C:00:8b:00
netdev=eth0
uprcw=setenv ethact $eth;setenv filename p4080ds/R_PPSXX_0xe/rcw_0xe_2sgmii_rev2_high.bin;setenv start 0xe8000000;protect off all;run upimage;protect on all

upucode=setenv ethact $eth;setenv filename fsl_fman_ucode_P4080_101_6.bin;setenv start 0xef000000;protect off all;run upimage;protect on all
usdboot=setenv ethact $eth;tftp 1000000 $dir/$bootfile;tftp 2000000 $dir/initramfs.cpio.gz.uboot;tftp c00000 $dir/p4080ds-usdpaa.dtb;setenv bootargs root=/dev/ram rw console=ttyS0,115200 $othbootargs;bootm 1000000 2000000 c00000;

Example 2: detect unused env vars:
=> grepenv etact
etact=FM1@DTSEC2
=>
Example 3: reveal hardcoded variables; e.g., for fdtaddr:
=> grepenv fdtaddr
fdtaddr=c00000
nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=$consoledev,$baudrate $othbootargs;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr - $fdtaddr
ramboot=setenv bootargs root=/dev/ram rw console=$consoledev,$baudrate $othbootargs;tftp $ramdiskaddr $ramdiskfile;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr $ramdiskaddr $fdtaddr
=> grep $fdtaddr
fdtaddr=c00000
my_boot=bootm 0x40000000 0x41000000 0x00c00000
my_dtb=tftp 0x00c00000 $prefix/p4080ds.dtb
nohvboot=tftp 1000000 $dir/$bootfile;tftp 2000000 $dir/$ramdiskfile;tftp c00000 $dir/$fdtfile;setenv bootargs root=/dev/ram rw ramdisk_size=0x10000000 console=ttyS0,115200;bootm 1000000 2000000 c00000;

This patch also enables the grepenv command by default on
corenet_ds based boards (and repositions the DHCP command
entry to keep the list sorted).
