hw/arm/raspi: Use BCM2708 machine type with pre Device Tree kernels When booting without device tree, the Linux kernels uses the $R1 register to determine the machine type. The list of values is registered at [1]. There are two entries for the Raspberry Pi: - https://www.arm.linux.org.uk/developer/machines/list.php?mid=3138 name: MACH_TYPE_BCM2708 value: 0xc42 (3138) status: Active, not mainlined date: 15 Oct 2010 - https://www.arm.linux.org.uk/developer/machines/list.php?mid=4828 name: MACH_TYPE_BCM2835 value: 4828 status: Active, mainlined date: 6 Dec 2013 QEMU always used the non-mainlined type MACH_TYPE_BCM2708. The value 0xc43 is registered to 'MX51_GGC' (processor i.MX51), and 0xc44 to 'Western Digital Sharespace NAS' (processor Marvell 88F5182). The Raspberry Pi foundation bootloader only sets the BCM2708 machine type, see [2] or [3]: 133 9: 134 mov r0, #0 135 ldr r1, =3138 @ BCM2708 machine id 136 ldr r2, atags @ ATAGS 137 bx r4 U-Boot only uses MACH_TYPE_BCM2708 (see [4]): 25 /* 26 * 2835 is a SKU in a series for which the 2708 is the first or primary SoC, 27 * so 2708 has historically been used rather than a dedicated 2835 ID. 28 * 29 * We don't define a machine type for bcm2709/bcm2836 since the RPi Foundation 30 * chose to use someone else's previously registered machine ID (3139, MX51_GGC) 31 * rather than obtaining a valid ID:-/ 32 * 33 * For the bcm2837, hopefully a machine type is not needed, since everything 34 * is DT. 35 */ While the definition MACH_BCM2709 with value 0xc43 was introduced in a commit described "Add 2709 platform for Raspberry Pi 2" out of the mainline Linux kernel, it does not seem used, and the platform is introduced with Device Tree support anyway (see [5] and [6]). Remove the unused values (0xc43 introduced in commit 1df7d1f9303aef "raspi: add raspberry pi 2 machine" and 0xc44 in commit bade58166f4 "raspi: Raspberry Pi 3 support"), keeping only MACH_TYPE_BCM2708.

qom: Less verbose object_initialize_child() All users of object_initialize_child() pass the obvious child size argument. Almost all pass &error_abort and no properties. Tiresome.

New convenience wrapper object_initialize_child() automates the size argument, and passes &error_abort and no properties.

qom: Drop parameter @errp of object_property_add() & friends The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().
