* libs/libc/modlib/modlib_load.c
- ET_DYN objects need to keep the relative displacement between the text
and data sections due to GOT references from the former to the latter.
This also implies that linking may require modification from the default
for the shared objects being produced. For example, default alignment may
mean nearly 64K of wasted space.

is a single allocation.

- Cater for ET_DYN objects having init and preinit sections
This commit adds support for 1 wire interface over serial driver. SAMv7
MCU does not have build in one wire support therefore external hardware
still has to be used (connection of RX/TX for example).

UART/USART peripheral can be used for more than just standard serial
driver. It can for example be used for 1 wire interface communication
(with external circuitry added). This changes the Kconfig for SAMv7 to
allow future implementation of these drivers. Now user can select
what kind of a driver he wants on UART/USART (serial or something else).

riscv-none-elf-ld: sotest.o: ABI is incompatible with that of the selected emulation:

There is a problem when vfork() calls execv() (or execl()) to start a new application:
When the parent thread calls vfork() it receives and gets the pid of the vforked task,
and not the pid of the desired execv'ed application.
see issue #3334

rndis header length is 36, L2 header is 14, IPv6 header is 40, tcp header is 56 when sack option count is 4(default max_ofosegs is 4). so the iob bufsize should greater than we need.

The previous iob_trimhead added dev->iob->io_offset, so if the
input frame is not merged into the ofo segment, we need to reset
dev->iob->io_offset so that the subsequent tcp_send can properly
assemble packets.

When the upper layer calls goldfish_camera_data_uninit, priv->capture_cb=NULL, but when there is data transmission in goldfish_camera_thread, priv->capture_cb will be called, which will cause a crash.

root cause:
work_cancel() can't cancel work completely, the worker may alreay be running.
resolve:
use work_cancel_sync() API to cancel the work completely

In the 'wd_timer',the callback function executed by 'wd_expiration' could call wd_start,and g_wdtickbase might be updated.Subsequently, g_wdtickbase is incremented by the value of ticks, causing g_wdtickbase to be greater than the actual passage of time.
