The Kconfig symbol SERIAL_S3C2412 got removed in commit da121506 ("serial: samsung: merge probe() function from all SoC specific extensions"). But it also added a last reference to that symbol. The commit and the tree make clear that CPU_S3C2412 should have been used instead.

The option allows you to remove TTY and compile without errors. This saves space on systems that won't support TTY interfaces anyway. bloat-o-meter output is below. The bulk of this patch consists of Kconfig changes adding "depends on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol such as SERIO, but most drivers "select SERIO" rather than "depends on SERIO", and "select" does not respect dependencies. bloat-o-meter output comparing our previous minimal to new minimal by removing TTY. The list is filtered to not show removed entries with awk '$3 != "-"' as the list was very long. add/remove: 0/226 grow/shrink: 2/14 up/down: 6/-35356 (-35350) function old new delta chr_dev_init 166 170 +4 allow_signal 80 82 +2 static.__warned 143 142 -1 disallow_signal 63 62 -1 __set_special_pids 95 94 -1 unregister_console 126 121 -5 start_kernel 546 541 -5 register_console 593 588 -5 copy_from_user 45 40 -5 sys_setsid 128 120 -8 sys_vhangup 32 19 -13 do_exit 1543 1526 -17 bitmap_zero 60 40 -20 arch_local_irq_save 137 117 -20 release_task 674 652 -22 static.spin_unlock_irqrestore 308 260 -48 Signed-off-by: NJoe Millenbach <jmillenbach@gmail.com> Reviewed-by: NJamey Sharp <jamey@minilop.net> Reviewed-by: NJosh Triplett <josh@joshtriplett.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>

These adapters use a "RocketPort 2" ASIC that is not compatible with the original RocketPort driver (CONFIG_ROCKETPORT). Tested with the RocketPort EXPRESS Octa DB9 and Quad DB9.

This special driver makes it possible to temporary use NMI debugger port as a normal console by issuing 'nmi_console' command (assuming that the port is attached to KGDB). Unlike KDB's disable_nmi command, with this driver you are always able to go back to the debugger using KGDB escape sequence ($3#33). This is because this console driver processes the input in NMI context, and thus is able to intercept the magic sequence. Note that since the console interprets input and uses polling communication methods, for things like PPP it is still better to fully detach debugger port from the KGDB NMI (i.e. disable_nmi), and use raw console. Usually, to enter the debugger one have to type the magic sequence, so initially the kernel will print the following prompt on the NMI debugger console: Type $3#33 to enter the debugger> For convenience, there is a kgdb_fiq.knock kernel command line option, when set to 0, this turns the special command to just a return key press, so the kernel will be printing this: Hit <return> to enter the debugger> This is more convenient for long debugging sessions, although it makes nmi_console feature somewhat useless. And for the cases when NMI connected to a dedicated button, the knocking can be disabled altogether by setting kgdb_fiq.knock to -1.

To avoid the possibility of regression, driver SC26XX left in the system to confirm the stability of the driver on platforms where it is being used.

The recent commit "serial: add irq handler for Freescale 16550 errata" would allow Kconfig choices that had 8250 support as a module and yet still try and build in the errata fix non-modular, resulting in build failures for some non-embedded PPC targets. Since we hook in the errata fix from legacy_serial.c, which is built only for PPC_UDBG_16550, and since the errata is only really relevant for SysRQ on serial console, tighten up the dependencies to be exactly that. We'll get coverage on the relevant Freescale boards because the Kconfig for their CPU types all select the PPC_UDBG_16550 option, and the defconfigs also all select the 8250_CONSOLE option. Also, the 8250_CONSOLE option has a strict dependency on "SERIAL_8250=y" which resolves the reported problem for non Freescale targets.

Sending a break on the SOC UARTs found in some MPC83xx/85xx/86xx chips seems to cause a short lived IRQ storm (/proc/interrupts typically shows somewhere between 300 and 1500 events). Unfortunately this renders SysRQ over the serial console completely inoperable. The suggested workaround in the errata is to read the Rx register, wait one character period, and then read the Rx register again. We achieve this by tracking the old LSR value, and on the subsequent interrupt event after a break, we don't read LSR, instead we just read the RBR again and return immediately. The "fsl,ns16550" is used in the compatible field of the serial device to mark UARTs known to have this issue. Thanks to Scott Wood for providing the errata data which led to a much cleaner fix.
