Subject: [U-Boot] [PATCH v2 17/18] stm32f7: add support for stm32f769 disco board
Date: Tue, 4 Apr 2017 14:45:19 -0700	[thread overview]
Message-ID: <1491342324-5820-18-git-send-email-vikas.manocha@st.com> (raw)
In-Reply-To: <1491342324-5820-1-git-send-email-vikas.manocha@st.com>

This board support stm32f7 family device stm32f769-I with 2MB internal Flash &
512KB RAM.
STM32F769 lines offer the performance of the Cortex-M7 core (with double
precision floating point unit) running up to 216 MHz.

To compile for stm32f769 board, use same defconfig as stm32f746-disco,
the only difference is to pass "DEVICE_TREE=stm32f769-disco".
