Subject: [U-Boot] [PATCH V2 3/5] ARM: tegra: derive CONFIG_SPL_MAX_SIZE instead of hard-coding it
Date: Thu, 18 Oct 2012 17:25:57 -0600	[thread overview]
Message-ID: <1350602759-22605-3-git-send-email-swarren@wwwdotorg.org> (raw)
In-Reply-To: <1350602759-22605-1-git-send-email-swarren@wwwdotorg.org>

From: Stephen Warren <swarren@nvidia.com>

For Tegra, the SPL and main U-Boot are concatenated together to form a
single memory image. Hence, the maximum SPL size is the different in
TEXT_BASE for SPL and main U-Boot. Instead of manually calculating
SPL_MAX_SIZE based on those two TEXT_BASE, which can lead to errors if
one TEXT_BASE is changed without updating SPL_MAX_SIZE, simply perform
the calculation automatically.
