+ 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.

+ ---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

- ---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

- An empty message will only clear the display at driver init time. Any other
- printf()-formatted message is valid with newline and escape codes.
