Dave Gerlach 37afff0d87 misc: sram: Integrate protect-exec reserved sram area type 
Introduce a new "protect-exec" reserved sram area type which is
makes use of the the existing functionality provided for the "pool"
sram region type for use with the genalloc framework and with the
added requirement that it be maintained as read-only and executable
while allowing for an arbitrary number of drivers to share the space.

This introduces a common way to maintain a region of sram as read-only
and executable and also introduces a helper function, sram_exec_copy,
which allows for copying data to this protected region while maintaining
locking to avoid conflicts between multiple users of the same space. A
region of memory that is marked with the "protect-exec" flag in the
device tree also has the requirement of providing a page aligned block
of memory so that the page attribute manipulation does not affect
surrounding regions.

Also, selectively enable this only for builds that support set_memory_*
calls, for now just ARM, through the use of Kconfig.

a user space API.
The ibmasm driver also enables the OS to use the UART on the
service processor board as a regular serial port. To make use of
this feature serial driver support (CONFIG_SERIAL_8250) must be

Most LCDs use a standard controller which supports hardware lines of 40
characters, although sometimes only 16, 20 or 24 of them are really wired
to the terminal. This results in some non-visible but addressable characters,
and is the case for most parallel LCDs. Other LCDs, and some serial ones,
however, use the same line width internally as what is visible. The KS0074
for example, uses 16 characters per line for 16 visible characters per line.
This option lets you configure the value used by your LCD in 'custom' profile.

---help---
Most LCDs use a single address bit to differentiate line 0 and line 1. Since
some of them need to be able to address 40 chars with the lower bits, they
often use the immediately superior power of 2, which is 64, to address the
next line.
If you don't know what your LCD uses, in doubt let 16 here for a 2x16, and

This describes the number of the parallel port pin to which the LCD 'RW'
signal has been connected. It can be :
0 : no connection (eg: connected to ground)
1..17 : directly connected to any of these pins on the DB25 plug
-1..-17 : connected to the same pin through an inverter (eg: transistor).
Default for the 'RW' pin in custom profile is '16' (INIT).
config PANEL_LCD_PIN_SCL

---help---
This describes the number of the parallel port pin to which the serial
LCD 'SCL' signal has been connected. It can be :
0 : no connection (eg: connected to ground)
1..17 : directly connected to any of these pins on the DB25 plug
-1..-17 : connected to the same pin through an inverter (eg: transistor).
Default for the 'SCL' pin in custom profile is '1' (STROBE).
config PANEL_LCD_PIN_SDA
depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" && PANEL_LCD_PROTO!="0"
int "Parallel port pin number & polarity connected to the LCD SDA signal (-17...17) "
range -17 17
default 2
---help---
This describes the number of the parallel port pin to which the serial
LCD 'SDA' signal has been connected. It can be :
0 : no connection (eg: connected to ground)
1..17 : directly connected to any of these pins on the DB25 plug
-1..-17 : connected to the same pin through an inverter (eg: transistor).
Default for the 'SDA' pin in custom profile is '2' (D0).
config PANEL_LCD_PIN_BL
depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"
int "Parallel port pin number & polarity connected to the LCD backlight signal (-17...17) "
range -17 17
default 0
---help---
This describes the number of the parallel port pin to which the LCD 'BL' signal
has been connected. It can be :
0 : no connection (eg: connected to ground)
1..17 : directly connected to any of these pins on the DB25 plug
-1..-17 : connected to the same pin through an inverter (eg: transistor).
Default for the 'BL' pin in custom profile is '0' (uncontrolled).
config PANEL_CHANGE_MESSAGE
depends on PANEL
bool "Change LCD initialization message ?"
default "n"
---help---
This allows you to replace the boot message indicating the kernel version
and the driver version with a custom message. This is useful on appliances
where a simple 'Starting system' message can be enough to stop a customer
from worrying.
If you say 'Y' here, you'll be able to choose a message yourself. Otherwise,
say 'N' and keep the default message with the version.
config PANEL_BOOT_MESSAGE
depends on PANEL && PANEL_CHANGE_MESSAGE="y"
string "New initialization message"
default ""
---help---
This allows you to replace the boot message indicating the kernel version
and the driver version with a custom message. This is useful on appliances
where a simple 'Starting system' message can be enough to stop a customer
from worrying.
An empty message will only clear the display at driver init time. Any other
printf()-formatted message is valid with newline and escape codes.
