b3e5cd17f6 microblaze: Fix compilation failure because of missing libdts
Microblaze platform can use CONFIG_OF_EMBED option
but also it is necessary to support boards
which don't want to use this option.
U-Boot doesn't compile dts/libdts.o for #undef CONFIG_OF_EMBED
case that's why it should be guarded by ifdef.

f8c1ed092c microblaze: Remove asm/bitops.h from asm/posix_types.h
The patch
"include/linux/byteorder: import latest endian definitions from linux"
(sha1: eef1cf2d5c)

Introduced a lot of compilation failures with unknow types.
include/linux/byteorder/big_endian.h:45:1: error: unknown type name '__le64'
include/linux/byteorder/big_endian.h: In function '__cpu_to_le64p':

include/linux/byteorder/big_endian.h:47:18: note: each undeclared identifier is reported only once for each function it appears in
include/linux/byteorder/big_endian.h:47:25: error: expected ';' before '__swab64p'
include/linux/byteorder/big_endian.h: At top level:
include/linux/byteorder/big_endian.h:49:1: error: unknown type name '__le64'
include/linux/byteorder/big_endian.h:53:1: error: unknown type name '__le32'
include/linux/byteorder/big_endian.h: In function '__cpu_to_le32p':

include/linux/byteorder/big_endian.h:61:1: error: unknown type name '__le16'
...

Removing asm/bitops.h solved this problem.

8b493a5236 common: Discard the __u_boot_cmd section

example the new axi_timer v1.02.a introduced in ISE 13.2.

9558b48af0 console: Implement pre-console buffer
Allow redirection of console output prior to console initialisation to a
temporary buffer.

To enable this functionality, the board (or arch) must define:
 - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer
 - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer
 - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes)

The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes
Any earlier characters are silently dropped.
