+Subject: [PATCH] CMakeLists.txt: fix paths when FTDIPP is set
+
+Use the same project name (i.e. libftdi1 and not libftdipp1) when FTDIPP
+is enabled as suggested by Aurelien Jarno in
+http://developer.intra2net.com/mailarchive/html/libftdi/2020/msg00044.html
+
+Without this change, the libftdi1.pc config file defines the include
+path as /usr/local/include/libftdipp1 while the ftdi.h file is actually
+installed in /usr/local/include/libftdi1
+
+This is an issue for example for libsigrok which will fail on:
+
+In file included from src/hardware/asix-sigma/protocol.c:27:
+src/hardware/asix-sigma/protocol.h:28:10: fatal error: ftdi.h: No such file or directory
+   28 | #include <ftdi.h>
+      |          ^~~~~~~~
+
+Fixes:

+Subject: [PATCH] python: update for SWIG 4.3
+
+SWIG 4.3 comes with an API change to the SWIG_Python_AppendOutput()
+function, so switch to the recommended SWIG_AppendOutput() instead.
+Because the new function is a macro in fact also switch to the  {..}
+delimiters as the code needs to be preprocessed. The change is
+compatible with the previous SWIG releases 4.2 and 4.1 at least.
+
+Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2319133

+		GUI Guider is a user-friendly graphical user interface development tool
+		from NXP that enables the rapid development of high quality display
+		with the open-source LVGL graphics library. GUI Guider's drag-and-drop
+		editor makes it easy to utilize the many features of LVGL such as
+		widgets, animations and styles to create a GUI with minimal or no coding
+		at all.
+		With the click of a button, you can run your application in a simulated
+		environment or export it to a target project. Generated code from GUI
+		Guider can easily be added to an MCUXpresso IDE or IAR Embedded
+		Workbench project, accelerating the development process and allowing you
+		to seamlessly add an embedded user interface to your application.
+		GUI Guider is free to use with NXP’s general purpose and crossover MCUs,

+	<longdescription>
+	Parapin makes it easy to write C code under Linux that controls individual pins on a PC parallel port. This kind of control is very useful for
+	electronics projects that use the PC's parallel port as a generic digital I/O interface. Parapin goes to great lengths to insulate the programmer
+	from the somewhat complex parallel port programming interface provided by the PC hardware, making it easy to use the parallel port for digital
+	I/O. By the same token, this abstraction also makes Parapin less useful in applications that need to actually use the parallel port as a parallel
+	port (e.g., for talking to a printer).

+Subject: [PATCH] build: Only enable -Werror for debug builds
+
+-Werror is very unhelpful for distributions and end users as newer
+compilers will raise warnings that the maintainers may not see. The
+warnings should get reported upstream, but they shouldn't block users
+from using the software.
+
+Rather than drop the flag entirely, I have enabled it only for debug
+builds, e.g. -DCMAKE_BUILD_TYPE=Debug.

+SDCC is a retargettable, optimizing Standard C (ANSI C89, ISO C99, ISO C11)
+compiler suite that targets the Intel MCS51 based microprocessors (8031, 8032,
+8051, 8052, etc.), Maxim (formerly Dallas) DS80C390 variants, Freescale
+(formerly Motorola) HC08 based (hc08, s08), Zilog Z80 based MCUs (Z80, Z180,
+SM83, Rabbit 2000, 2000A, 3000A, TLCS-90), Padauk (pdk14, pdk15) and
+STMicroelectronics STM8. Work is in progress on supporting the Padauk pdk13 and
+MOS 6502 targets; Microchip PIC16 and PIC18 targets are unmaintained. SDCC can
+be retargeted for other microprocessors.

+		Next generation UI editor for individuals and professionals to design
+		and develop beautiful UIs for your embedded devices quickly and easily.
+		SquareLine Studio is specially developed for designers so as to
+		implement their plans in the most efficient way and to take the most off
+		the programmers' shoulders. SquareLine Studio uses the fully open source
+		LVGL UI library which makes it possible to control the whole project
+		because there is no Lib file generated code set. Meanwhile, it gives
+		great performance on low performance devices.
+		SquareLine Studio supports exporting C and MicroPyton source code.
+		If you don't need the low level C programming, you can create your
+		project in the simplyfied version of the well-known and commonly used
+		Python scripting language, MicroPython. The advantage of MicroPython
+		compared to C programming is that it can process commands in real time.
+		For instance if we would like to add a button to the screen of a project
+		running on a device, we should send the Add button command to the system
+		so as to make the button appear immediately on the device.
+	</longdescription>
+	<longdescription lang="zh">
+		下一代的UI编辑器，适用于个人和专业人士，可以快速、轻松地为您的嵌入式设备
+		设计和开发美观的用户界面。SquareLine Studio是专门为设计师开发的，以便以
+		最高效的方式实现他们的计划，同时尽量减轻程序员的负担。SquareLine Studio
+		使用完全开源的LVGL UI库，这使得可以控制整个项目，因为不会生成Lib文件
+		编码集。同时，它在低性能的设备上表现出色。
+		SquareLine Studio支持导出C和MicroPython源代码。如果您不需要低级C编程，
+		您可以使用众所周知且常用的Python脚本语言的简化版本MicroPython创建您的
+		项目。与C编程相比，MicroPython的优势是它可以实时处理命令。例如，如果我们
+		想在运行在设备上的项目的屏幕上添加一个按钮，我们应该向系统发送添加按钮的
+		命令，以便立即在设备上显示该按钮。

+Subject: [PATCH 1/2] nandpart: fix strncpy compiler warning
+
+More recent versions of GCC warns about the usage of strncpy in
+nandpart.c: we actually only (need to) copy the stub string part of the
+magic string, without the terminating NUL character. This is fine in
+our particular case, but raises the compiler's eyebrows:
+===================
+nand-part.c: In function '_get_mbr':
+nand-part.c:93:4: warning: 'strncpy' output truncated before terminating
+                  nul copying 8 bytes from a string of the same length
+                  [-Wstringop-truncation]
+   93 |    strncpy((char *)mbr->magic, MBR_MAGIC, 8);
+      |    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+===================
+
+Switch to the more fitting memcpy() here to avoid the warning.

+  zmac is a Z80 macro cross-assembler. It has all the features you'd expect.
+  It assembles the specified input file and produces raw binary output.
+  (It can optionally produce CP/M-style Intel hex format.) By default it
+  also produces a nicely-formatted listing of the m/c alongside the source.
+
+  As well as normal Z80 programs, zmac lets you write 8080 programs in Z80
+  assembly.
