ARM: lh7a40x: remove unmaintained platform support
lh7a40x has only been receiving updates for updates to generic code. The last involvement from the maintainer according to the git logs was in 2006. As such, it is a maintainence burden with no benefit. This gets rid of two defconfigs. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

44 help
45 Say Y here if your bootloader sets the SROMLL bit(s) in
46 the SDRAM controller, organizing memory as a contiguous
47 array. This option will disable sparse memory support
48 and force the kernel to manage all memory in one node.
49
50 Setting this option incorrectly may prevent the kernel
51 from booting. It is OK to leave it N.

60 Say Y here to produce compact memory node tables. By
61 default pairs of adjacent physical RAM banks are managed
62 together in a single node, incurring some wasted overhead
63 in the node tables, however also maintaining compatibility

11
12 This SSP header is available throughout the kernel, for this
13 machine/architecture, because drivers that use it may be dispersed.
14
15 This file was cloned from the 7952x implementation. It would be
16 better to share them, but we're taking an easier approach for the
17 time being.

9 DESCRIPTION
10 -----------
11
12 Only one panel may be defined at a time.
13
14 The pixel clock is calculated to be no greater than the target.
15
16 Each timing value is accompanied by a specification comment.
17
18 UNITS/MIN/TYP/MAX
19
20 Most of the units will be in clocks.
21
22 USE_RGB555
23
24 Define this macro to configure the AMBA LCD controller to use an
25 RGB555 encoding for the pels instead of the normal RGB565.
26
27 LPD9520, LPD79524, LPD7A400, LPD7A404-10, LPD7A404-11
28
29 These boards are best approximated by 555 for all panels. Some
30 can use an extra low-order bit of blue in bit 16 of the color
31 value, but we don't have a way to communicate this non-linear
32 mapping to the kernel.

13/* NOTES
14 -----
15
16 o *** This driver is cribbed from the 7952x implementation.
17 Some comments may not apply.
18
19 o This driver contains sufficient logic to control either the
20 serial EEPROMs or the audio codec. It is included in the kernel
21 to support the codec. The EEPROMs are really the responsibility
22 of the boot loader and should probably be left alone.
23
24 o The code must be augmented to cope with multiple, simultaneous
25 clients.
26 o The audio codec writes to the codec chip whenever playback
27 starts.
28 o The touchscreen driver writes to the ads chip every time it
29 samples.
30 o The audio codec must write 16 bits, but the touch chip writes
31 are 8 bits long.
32 o We need to be able to keep these configurations separate while
33 simultaneously active.
