Subject: [PATCH 01/10] board: ti: am62x: Init DRAM size in R5/A53 SPL
Date: Fri, 12 Jan 2024 12:17:50 +0530	[thread overview]
Message-ID: <20240112064759.1801600-2-s-vadapalli@ti.com> (raw)
In-Reply-To: <20240112064759.1801600-1-s-vadapalli@ti.com>

From: Kishon Vijay Abraham I <kishon@ti.com>

Call dram_init_banksize() from spl_board_init() otherwise TFTP download
fails with error "TFTP error: trying to overwrite reserved memory..."
due to lmb_get_free_size() not able to find unreserved region due
to lack of DRAM size info. Required to support Ethernet boot on AM62x.
