back at physical address 0x2007C000 and 0x20080000 (i.e. right below and right
above a 512 KiB boundary). Memory from those two blocks is considered
continuous when assigned to a heap.
In the protected build mode, when the memory protection unit is used, though,
it must be split into two MPU regions. This is because MPU regions must be
naturally aligned, and the 32KiB continuous address space of the two 16KiB AHB
SRAM blocks does not start at an address divisible by 32KiB.
The only other configurations that use protected build mode on lpc17xx are
currently open1788/knsh and open1788/knxterm. The LPC1788 has the AHB SRAM
blocks mapped more sanely (from an MPU region point of view), which is
probably why no problems emerged here. Both still compile with my change and
other than wasting an MPU region (which would otherwise remain unused) should
work fine. That said, I have no hardware to confirm.
arch/arm/src/am335x: Add logic to map the framebuffer to a non-cached, non-buffered memory region.
arch/arm/src/am335x: Remove struct am335x_fbinfo_s. Replaced with configuration settings that provide the same information.
Squashed commit of the following:
arch/arm/src/am335x/am335x_lcdc.c: LCD driver now compiles.
arch/arm/src/am335x/am335x_lcd.c: This brings the LCD driver to code complete. Have not yet attempted to compile.
arch/arm/src/am335x/am335x_edid.c: Framebuffer is pre-allocated. In verification of video mode, include a test to assure that the video mode can be supported by the pre-allocated framebuffer memory.
arch/arm/src/am335x/am335x_lcd.c: At a little bit of LCD initialization logic. There is a long way to go.
arch/arm/src/am335x/am335x_edid.c: Add am335x_lcd_videomode() which provides an alternative way of initializing the LCD controller.
arch/arm/src/am335x/am335x_edid.c: edit.h has move to include/nuttx/video.
arch/arm/src/am335x/hardware/am335x_cm.h: Fix a typo in a macro name.
arch/arm/src/am335x/am335x_edid.c: Integrate video/edid support.
arch/arm/src/am335x/am335x_edid.c: Fall back to VGA mode is not valid videomode is availabe in the EDID data.
arch/arm/src/am335x/am335x_edid.c: Fixes for a partially clean compile.
arch/arm/src/am335x/am335x_edid.c: Add basic logic to convert EDID montor descriptions into a form usable for LCD configuration.
arch/arm/src/am335x: Add framework (only) for an LCD driver. Initial commit is simply the LPC54 framebuffer driver with naming changes.
