net: dns: fix for DNS queries sent to the wrong MAC address
When a DNS query is sent out, the ethernet packet can get directed to
the MAC address of a server that was communicated to before. This is
wrong when the previously stored MAC address corresponds to a different
server's IP address, i.e. when the IP address of the previous and the
current communication are different.
The error can get reproduced by running a sequence of e.g. a TFTP
download and a DNS query, where the TFTP and DNS servers reside on
individual machines.
The fix is to clear the server's MAC address that might be left from a
previous operation, and to fetch the peer's MAC address in a new ARP
lookup, before the DNS query is sent. This is the approach taken in
other network services, like 8e52533d1095 ("net: tftpsrv: Get correct
client MAC address").

rtl8169: Defer network packet processing
When network protocol errors occur (such as a file not being found on a

up calling the driver's .halt() implementation. However, after that the
device no longer has access to the memory buffers and will cause errors
such as this in the rtl_recv() function when trying to hand descriptors
back to the device:

kconfig: add CONFIG_SYS_{ARCH, CPU, ...} type def to arch/Kconfig
This commit adds the type definitions (+ help messages) of
CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} to arch/Kconfig,
which would save lots of type defs for taget boards.
(See also the next commit.)
The boards using CONFIG_SYS_DV_NOR_BOOT_CFG (i.e. calimain,
da850evm_direct_nor and enbw_cmc) had the _start symbol defined after
the CONFIG_SYS_DV_NOR_BOOT_CFG word rather than before it in
arch/arm/lib/vectors.S. Because of that, if by lack of luck
'gd->mon_len = (ulong)&__bss_end - (ulong)_start' (see setup_mon_len())
was a multiple of 4 kiB (see reserve_uboot()), then the last BSS word
overlapped the first word of the following reserved RAM area (or went
beyond the top of RAM without such an area) after relocation because
__image_copy_start did not match _start (see relocate_code()).
This was broken by commit 41623c9 'arm: move exception handling out of
start.S files', which defined _start twice (before and after the
CONFIG_SYS_DV_NOR_BOOT_CFG word), then by commit 0a26e1d 'arm: fix a
double-definition error of _start symbol', which kept the definition of
the _start symbol after the CONFIG_SYS_DV_NOR_BOOT_CFG word. This new
commit fixes this issue by restoring the original behavior, i.e. by
defining the _start symbol before the CONFIG_SYS_DV_NOR_BOOT_CFG word.
Some boards, like mx31pdk and tx25, require the beginning of the SPL
code to be position-independent. For these two boards, this is because
they use the i.MX external NAND boot, which starts by executing the
first NAND Flash page from the NFC page buffer. The SPL then needs to
copy itself to its actual link address in order to free the NFC page
buffer and use it to load the non-SPL image from Flash before running
it. This means that the SPL runtime address differs from its link
address between the reset and the initial copy performed by
board_init_f(), so this part of the SPL binary must be
position-independent.
This requirement was broken by commit 41623c9 'arm: move exception
handling out of start.S files', which used an absolute address to branch
to the reset routine. This new commit restores the original behavior,
which just performed a relative branch. This fixes the boot of mx31pdk
and tx25.
