Subject: [PATCH] ARM: dts: exynos4212-tab3: Limit usable memory range
|
|
|
|
The stock bootloader on the Samsung Galaxy Tab 3 8.0 provides an
|
|
incorrect available memory range over ATAG_MEM. Limit the usable
|
|
memory in the DTS to prevent it from doing so, without having to
|
|
disable ATAG support.
