These wrappers are not needed as CC doesn't need to be a single word.
a53b084e49 which introduced the wrappers
doesn't explain why they were really needed and why only for the target
and not for the host.
Moreover, name of the wrappers breaks a ccache assumption: since
v4.0-3-g6a92b4cd3a67 it has special handling for "chained" invocation
such as "ccache ccache gcc" where it skips all the "ccache*" names in
the middle and proceeds to run as if it was started as "ccache
gcc"[1][2].
This becomes important when a build system sees ccache in the PATH and
automatically enables it by prepending to CC. An example of such a
system would be autosetup as used by jimtcl. With the wrappers it breaks
as the command line ends up being just "ccache -Os..." because
"ccache_cc" gets skipped as it starts with "ccache".

We can increase the efficiency of rx path by using buffers to receive
packets then build SKBs around them just before passing into the network
stack. In contrast, preallocating SKBs too early reduces CPU cache
efficiency.

potential optimizations.

bmips is using Broadcom B53 DSA driver which means the ethernet driver
must compensate for 6 bytes tags from the internal switch.
This means using NET_IP_ALIGN actually misaligns the skb, lowering
performance significantly. Therefore napi_alloc_skb() which uses
NET_IP_ALIGN is changed to netdev_alloc_skb().
Performance in iperf3 is increased from ~47Mbps to 52Mbps.

* WiFi: MT7615DN (2.4GHz+5Ghz) with DBDC
* Ethernet: 4x1000M LAN, 1x 1000M WAN
* LEDs: Power Blue+Orange,Wan Blue+Orange,WPS Blue,"2.4G"Blue, "5G" Blue,

* Buttons: Reset,WPS, Wifi
* Serial interface: on board but not populated, pinout (from the DC jack
side to the WAN port side) is "3.3V Input Output Gnd". Baud rate is 57600,
settings are 8 data bits, no parity bit, one stop bit, and no flow control.
Stock flash layout:
```
GD25Q128C(c8 40180000) (16384 Kbytes)
mtd .name = raspi, .size = 0x01000000 (16M) .erasesize = 0x00010000 (64K)
.numeraseregions = 0
Creating 7 MTD partitions on "raspi":
0x000000000000-0x000001000000 : "ALL"

0x000000030000-0x000000040000 : "Config"

0x000000060000-0x000000fb0000 : "Kernel"
0x000000fb0000-0x000001000000 : "Private"
```
The kernel partition will be replaced with the OpenWrt image, the other
partitions are left untouched.
"Config2" seems to be the config storage used by the stock firmware.
"Private" is a 320kB empty JFFS2 partition that comes with the stock
firmware. One can get a larger space for OpenWrt by merging it with
"Kernel".
OpenWrt flash layout:
```
0x000000000000-0x000000030000 : "u-boot"
0x000000030000-0x000000040000 : "u-boot-env"
0x000000040000-0x000000050000 : "factory"
0x000000050000-0x000000060000 : "config2_stock"
0x000000060000-0x000000fb0000 : "firmware"
0x000000fb0000-0x000001000000 : "private_stock"
```
The OpenWrt image must have 96 bytes of padding in the header.
MAC addresses on OEM firmware:
| | location on the flash | notes |
|------ |----------------------- |---------- |
| lan (eth2) | factory + 0xe000 | on label |
| wan (eth3) | factory + 0xe006 | |
| 2.4g (rax0) | not on flash | lan + 1 |
| 5g (ra0) | not on flash | lan + 2 |
Mac addresses of the 2.4g and 5g interface are stored as ASCII strings in
the u-boot-env partition, but they are not used. OpenWrt calculates
Wifi Mac addresses based on the LAN Mac.
Flash and test instructions:
Flash the encrypted image (available in the OpenWrt forum) through the
stock D-Dink web interface.
1. Open the case, and solder the 4-pin header near the WAN port.
2. Connect it to a USB-UART TTL (3.3V) adapter, no need to connect VCC.
3. Open a terminal emulator (e.g. `screen /dev/ttyUSB0` on linux) with
the settings mentioned above.
4. Setup a TFTP server on your PC that can serve
`xxx-ramips-mt7621-dlink_dir-853-a1-initramfs-kernel.bin`.
5. Connect any LAN port to your PC and set a static IPv4 address to
192.168.0.101 (netmask 255.255.255.0).
6. Power on the device and keeps pressing 1 until you see the prompt.
7. Use default IP addresses and enter the file name accordingly, then hit
enter.
8. Wait until it boots to OpenWrt, the default IP address is 192.168.1.1,
you need to change your PC network adapter to use DHCP in order to access
LUCI.
9. So far, the OpenWrt runs in RAM and the flash contents are not touched.
You can try OpenWrt without having to overwrite the stock firmware, a
reboot clears all changes.
10. Optionally, backup the stock firmware (the "firmware" partition) in
Luci.
11. To permantly install OpenWrt to the device , click
on "System -> Backup/Flash Firmware" in Luci and flash
`xxx-ramips-mt7621-dlink_dir-853-a1-squashfs-sysupgrade.bin`
Known problems:
* WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network,
you need to config it manually in LUCI.
* If you see jffs2 related warnings/errors after updating from the stock
web interface, you need to do a reset in LUCI. The error will be gone after
a cold reboot.

This fixes spurious boot-errors with some ath79 MIPS 74Kc boards such
as the AC Lite as well as Archer C7 v2.
The missing barrier leads to the icache flush being executed before the
dcache writeback, which results in the CPU executing the dummy infinite
loop in tlbmiss_handler_setup_pgd.
Applying this patch from upstream ensures the dcache is written back
before flushing the icache.
