Console: remove deprecated finish_console_register

2019-04-03T13:55:18Z

The old version of the macro is deprecated. Commit cc5859ca19ff ("Multi-console: Deprecate the `finish_console_register` macro") provides more details. Change-Id: I3d1cdf6496db7d8e6cfbb5804f508ff46ae7e67e Signed-off-by: Ambroise Vincent

Sanitise includes across codebase

2019-01-04T10:43:17Z

Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

Multi-console: Deprecate the `finish_console_register` macro

2018-10-19T16:34:52Z

The `finish_console_register` macro is used by the multi console framework to register the `console_t` driver callbacks. It relied on weak references to the `ldr` instruction to populate 0 to the callback in case the driver has not defined the appropriate function. Use of `ldr` instruction to load absolute address to a reference makes the binary position dependant. These instructions should be replaced with adrp/adr instruction for position independant executable(PIE). But adrp/adr instructions don't work well with weak references as described in GNU ld bugzilla issue 22589. This patch defines a new version of `finish_console_register` macro which can spcify which driver callbacks are valid and deprecates the old one. If any of the argument is not specified, then the macro populates 0 for that callback. Hence the functionality of the previous deprecated macro is preserved. The USE_FINISH_CONSOLE_REG_2 define is used to select the new variant of the macro and will be removed once the deprecated variant is removed. All the upstream console drivers have been migrated to use the new macro in this patch. NOTE: Platforms be aware that the new variant of the `finish_console_register` should be used and the old variant is deprecated.

pl011: cnds: cbmem: 16550: Fix comments

2018-10-12T13:47:41Z

The comments with the prototypes of the register functions of the console drivers are incorrect. The arguments are wrong. This patch fixes them. Change-Id: I38c4b481ee69e840780111c42f03c0752eb6315c Signed-off-by: Antonio Nino Diaz

drivers: ti: uart: Add TI specific 16550 initialization

2018-06-11T19:26:32Z

On TI platforms the UART is disabled by default and must be explicitly enabled using the MDR1 register. NOTE: The original definition of http://www.ti.com/lit/ds/symlink/pc16550d.pdf has no MDR register, but many TI SoCs implementing 16550 do have a quirky MDR register implemented. So, this should be enabled with TI_16550_MDR_QUIRK NOTE: In such implementation, the CSR register does not exist. Signed-off-by: Benjamin Fair Signed-off-by: Nishanth Menon Signed-off-by: Andrew F.

drivers: ti: uart: Update 16550 UART driver to support MULTI_CONSOLE_API

2018-01-19T23:21:12Z

This patch updates the TI 16550 console driver to support the new console API. The driver will continue to support the old API as well by checking the MULTI_CONSOLE_API compile-time flag. Change-Id: I60a44b7ba3c35c74561824c04b8dbe3e3039324c Signed-off-by: Julius Werner

drivers: ti: uart: remove UART_FCR writes

2017-04-21T22:18:48Z

This patch removes the code that touched UART_FCR, from console_core_putc(). The check for whether transmit FIFO is full is sufficient before writing to UART TX FIFO. In fact setting UARTFCR_TXCLR immediately after a byte is written to FIFO might even result in loss of that byte, if UART hasn't sent that byte out yet. Signed-off-by: Varun Wadekar
