4f67a6c76d cc3200: Remove TI cc3200 SOC and LaunchXL board support
Per ZEP-1958, Phase 2 of adding CC3220sf LaunchXL support,
was to "deprecate the CC3200 launchxl support in Zephyr
(redundant to the CC3220)."

Effectively, the CC3220 SOC replaces the CC3200.

This patch removes the following:
* the imported CC3200 SDK
* CC3200 SOC, board, DTS files.
* adjusts other files where cc3200 was mentioned.

Also, it fixes explicit references to CC3200 in generic
CC32xx driver files.

5eef82db68 kconfig: serial: esp32: Make driver depend on SOC_ESP32
The ESP32 UART driver can only be used on the ESP32 SoC AFAICT. But it
did not have a depend clause so it was polluting the options of other
platforms.

With this patch the ESP32 driver will no longer be exposed to users of
non-ESP32 devices.

271c518ec6 uart_esp32: alter the uart.h include order to avoid warning
The esp-idf package contains on the BSP a definition of the BIT macro

This generates a compile warning on the re-definiton of BIT by the

37ea77173c drivers: esp32: Add minimal UART driver based on ROM routines
This is a minimal driver enabling console output during the port
bringup.  While the driver works, only one of the three UART devices
are supported, and there isn't any way to change any parameters or

0fdc9b5b12 drivers: serial: Clarify usage of TX/RX IRQ predicates.
uart_irq_tx_empty() function proved to be problematic: its semantics
was not documented properly, and many hardware uses terminology like
"TX register empty" to signify condition of TX register being ready
to accept another character (what in Zephyr is tested with
uart_irq_tx_ready()). To avoid confusion, uart_irq_tx_empty() was
renamed to uart_irq_tx_complete(), propagating to drivers/serial
device methods.

The semantics and usage model of all of uart_irq_rx_ready(),
uart_irq_tx_ready(), uart_irq_tx_complete() is now described in
detail.

2506e2738e stm32: Don't perform any side effects in irq_update().
The purpose of irq_update() is to cache value of UART IRQ status
register for devices which needs such caching. No other driver
performs any other side effects in this call. For STM32, clearing
TC (tx complete) bit was introduced in 8c079e91c9
which is otherwise titled as a conversion to STM32Cube HAL. Thus,
there does not seem to be specific reasons why this code was added.
On the other hand, it leads to behaviorial artifacts when dealing
with interrup-driven UART code (specific issue seen was delaying
of transmitting every other character).

abf284e9fd Revert "serial: stm32: Give H/W a chance to set the TXE bit on transfer"
Don't busy-wait in uart_stm32_fifo_fill(), this routine is supposed
to be called on IRQ, and the waiting loop was shown to interfere
with interrupt-driven UART handling.

The original problem mentioned in the patch being reverted ("it is
possible to evaluate the TXE bit *before* H/W has had the
opportunity to detect that data is being processed") may still
exist and may require handling in a different way. The most obvious
way is to replace "while" loop with "if", because STM32 doesn't
have multi-level FIFO anyway. But I was dissuaded to include such a
change as part of this patch, so it's left for future analysis.

This reverts commit 49c2858d94.

types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some

This patch removes the cc32xx related fixup file

Since cc32xx has DTS files, and since HAS_DTS will always be true,
it also removes the 'if !HAS_DTS' blocks from the cc32xx Kconfig
files.
