resource: dev_request_mem_region: fix return value for MIPS ...

The commit

    commit 0d7a213
    Author: Antony Pavlov <antonynpavlov at gmail.com>
    Date:   Wed Sep 10 11:42:19 2014 +0400

        MIPS: dts: use physical addresses (as Linux does)

        With IOMEM() adapted for MIPS we can use physical addresses
        in device tree reg property.

has switched MIPS dts files to physical addresses usage.

The patch was tested on qemu, but qemu malta board is tolerant
of using physical addresses for accesing to device
(Ingenic JZ4755 and JZ4780 processors are tolerant too!).
But other CPUs (e.g. Loongson LS1B) can throw an exception
in this situation.

Additional physical address to virtual address translation
on MIPS is needed.

We already have this in include/common.h

    #if defined(CONFIG_MIPS)
    #include <asm/addrspace.h>

    #define IOMEM(addr) ((void __force __iomem *)CKSEG1ADDR(addr))
    #else
    #define IOMEM(addr) ((void __force __iomem *)(addr))
    #endif

So use IOMEM() to fix dev_request_mem_region() return value.

kbuild: create a build directory automatically for out-of-tree build ...

Kbuild supports saving output files in a separate directory.
But the build directory must be created beforehand. For example,

  $ mkdir -p dir/to/store/output/files
  $ make O=dir/to/store/output/files defconfig

Creating a build directory automatically would be useful.

kbuild: move asm-offsets.h rule to ./Kbuild ...

Currently, MIPS is the only architecture that needs
include/generated/asm-offsets.h, but we have got ./Kbuild file now.

It is a good reason to move asm-offsets.h rule from arch/mips/Makefile
to ./Kbuild and add dummy asm-offsets.c for the other architectures.
asm-offsets.h would be useful for all the architectures.

This commit does not implement include/generated/bounds.h,
but if necessary, it is easy to implement it.

net: cpsw: ignore error on slave setup ...

The CPSW has two slaves. When one of them fails to setup continue
anyway with the other one. This fixes a crash in the beaglebone black
which only has one slave connected. The code doesn't find a phy on
the second slave and bails out, but the error path is broken: It frees
the private data structures which contains used resources.

net: smc1111: fix memory congestions ...

As the SMC1111 has a shared pool of 2k memory buckets for both
transmission and reception, and as there are variants which have as few
as 4 buckets in total, the memory pool can be hogged by unclaimed
receptions, and impeed any further transmission.

This happens on the zylonite pxa board, where 4 packets, most probably
icmp and arp, fill the 4 buckets, preventing any further ethernet
transmission, and stalling the driver.

The fix is rather rough : whenever all the buckets are filled by
reception packets, and if a transmission is required, the transmission
code path will empty up all received packets.

am33xx_of_register_bootdevice() when the system is booted from eMMC.

commands: loady: fix bug with netconsole ...

Netconsole doesn't have a baudrate. Loady supposes a console has one,
and tries to compute the console's baudrate variable value, regardless
of its existence.

This triggers a NULL pointer dereference on netconsole. If attempting
loady on a netconsole is a bit useless, barebox should not panic. Fix
this by checking the variable exists before reading its value.
