[U-Boot] Some SuperH boards are broken

[Masahiro Yamada]

Hello Nobuhiro

I cannot compile sh7752evb and sh7757lcr boards
because of the following error:

sh_eth.c: In function 'sh_eth_send':
sh_eth.c:57:2: warning: implicit declaration of function 'dcache_wback_range' [-Wimplicit-function-declaration]
drivers/net/built-in.o: In function `sh_eth_send':
/home/masahiro/u-boot-log/u-boot-4/drivers/net/sh_eth.c:87: undefined reference to `dcache_wback_range'
drivers/net/built-in.o: In function `sh_eth_rx_desc_init':
/home/masahiro/u-boot-log/u-boot-4/drivers/net/sh_eth.c:276: undefined reference to `dcache_wback_range'


I grepped the whole tree and the definition of "dcache_wback_range"
function is surely missing.

Unfortunately, no board maintainter is assigned for these two boards.
Could you fix them?
Or if you can't fix this issue, please both of the two boards.


And we have newly another warning message:

time.c:14:2: warning: #warning "CONFIG_SYS_HZ must be 1000 and should not be defined by platforms" [-Wcpp]
for rsk7203, rsk7264, rsk7269 boards.

We need to fix boards which use CONFIG_SYS_HZ other than 1000.


Best Regards
