[U-Boot] [PATCH 0/6] Add stmf429-evaluation board support

[patrice.chotard at st.com]

From: Patrice Chotard <patrice.chotard@st.com>

This series add support for stmf429-evaluation board.

Before adding this board support, the clk_stm32f driver must be updated
to be able to retrieve external oscillator frequency (HSE) from device tree.
This because stm32f429-evaluation board doesn't use a 8 Mhz external
oscillator as all STM32F4 board supported (stm32f429-disco and stm32f469-disco).

[U-Boot] [PATCH 1/6] ARM: dts: stm32: add "u-boot, dm-pre-reloc" for clk_hse in stm32f7-u-boot

[patrice.chotard at st.com]

From: Patrice Chotard <patrice.chotard@st.com>

In order to retrieve the clk_hse fixed clock phandle in clk_stm32f driver,
add "u-boot,dm-pre-reloc" property in Uboot specific DT file.

[U-Boot] [PATCH 2/6] clk: stm32: retrieve external oscillator frequency from DT

[patrice.chotard at st.com]

From: Patrice Chotard <patrice.chotard@st.com>

All current STM32F4 supported boards uses a 8MHz external oscillator.
All current STM32F7 supported boards uses a 25MHz external oscillator.

In order to introduce the new stm32f429-evaluation board which uses a
25MHz external oscillator without creating a dedicated struct
stm32_clk_info for this board, retrieve the external oscillator
frequency from DT and set pll_m accordingly to obtain 1MHz for the VCO.
